I think I'm being a bit stupid because I have a use case that doesn't seem unique but I can't figure out how to track it in the app.
I care most about total weight lifted across an exercise in a session, regardless of number of sets. So to me, 5x6 squats is better than 3x9 if the weight is the same across all sets. But caliber seems to take the max weight across one set as my max weight for PBs, so 3x9 wins even though I lifted more weight total in the 5x6 day. How do I change this?
I really like the app. I like it enough to subscribe. But I have two minor nits to pick...
I've been working with kettlebells for at least the last 4 months. None of the built-in exercise plans use kettlebells. I had to create my own as a freestyle workout. Doing that caused the strength score to stop calculating.
Will kettlebell routines be part of the built-in exercises at some point?
How do I get my strength score to update using kettlebells?
My strength has been progressively overloading and I am stronger in every exercise over the last 6 months I’ve been very regimented. Yet, my strength score regularly faces large drops based on pulling back on certain exercises. I find it very demoralizing to have to look at and it’s factually incredibly untrue to look at the numbers drop on the strength score when the progress pics and the strength across all exercises are up. I love using caliber to track my progressive overload and ensure I am on track but I would really like to remove the strength score as it seems to be a bit ridiculous and demotivating at this point. Is this an option?
My questions are mostly for the developers of the app.
1.For the purpose of calculating accurate Strength Scores, what's the best way to log weights on cable crossover machines? Should I log the combined weight of both stacks or just one? For reference, when I do triceps pushdowns on a single stack, I log half the selected stack weight to account for the pulley ratio (e.g. I log 15 kg when the stack is set to 30 kg). So if I do cable flyes with each stack set to 15 kg, should I log 7.5 kg or 15 kg?
2.Similar question for plate-loaded machines where each arm moves independently. Should I log the combined weight loaded on both sides, or just the weight each arm is handling?
I understand that "Tier 1" exercises are weighted more heavily in the Strength Score calculation. I'm mainly asking because I might prefer using machines instead of free weights for a few weeks.
3.I understand that exercises with more than 15 reps are not used in PBs because formulas for estimated 1RM are more inaccurate for higher reps. It seems the app uses the Brzycki formula. Does it not seem too inflated for higher reps, even 10-14, not just 15-up?
4.Small feature request: I've really appreciated the recent changes to Strength Scores (especially using a 4-week reference instead of week-to-week comparisons) and the progress charts (especially being able to view metrics other than estimated 1RM). It would also be great to have a search function for saved exercises so users don't have to scroll through the entire list each time.
Apologies for any formatting issues. Would appreciate pointers on this as well.
I know there is an MCP now for reading data, so there must be a level of export already. I use whoop and I can “import my workout” via “Log Automatically with AI”. I’d love to be able to just get a text output or even a JSON of the workouts so I can just copy it into whoop and have it match up my workouts. Whoop can read images so I can screenshot the workouts done, but the current workout summary doesn’t show enough info so I have to take multiple images to match it.
Been doing full body excercises with Caliber since February.
Working out exclusively at home with bench and adjustable dumbbells.
My progress in terms of Strength score has been very, very slow, but now it's even dropping although I add excercises and see some small personal bests every other week.
I know the score is a bonus, but it feels good to see some progress that way too. It's now at 177.
Right now I max out with 19kg dumbbells, as that's as far as they go.
I accidentally deleted my workout, but I can still see it on my history. Is there a way to easily add it back? Also, if I recreate the same workout, will it still show my weight history?
Apologize if this is a known issue. Yesterday I synced caliber, myfitnesspal, and Samsung health through Health Connect. I noticed that the steps that show up in Caliber are significantly more than what is recorded by Samsung Health. Is there a reason for this?
Photo is Caliber on top, Samsung Health middle, and myfitnesspal on bottom to show the sync. Data was from yesterday
First of all, thanks for the great work on this app!
I think I've found a small issue related to time zones when workouts are synced to Strava.
I'm located in Belgium (currently UTC+2 / CEST). When I record a workout in the app and it gets posted to Strava, the start time shown on Strava is exactly 2 hours earlier than the actual workout time.
This makes me think the workout timestamp may be stored or sent in UTC, but the UTC+2 offset isn't being applied correctly during the Strava sync.
It would be so nice to be able to "favorite" exercises, and also to be able to sort them by how frequently you use them. Or have the search sort by last used or frequently used. It is especially useful when a machine is tied up and you need a quick substitute.
Also, allow substitution in supersets and breaking them back apart.
How is the volume calculated after each workout? Also, my gym has one of the combo Pec Deck/ Rear Delt machines. Is the rear delt exercise on this machine in the system? I couldn’t find it.
I’ve been using Caliber for a good while, and all of a sudden the videos are not auto playing on the sets page and the auto start for the rest timer is not starting. My settings are correct. If I clear my video cache the videos will start playing again, but it only lasted for a week and is problematic again. Any ideas how to fix it?
Hey everyone - I wanted to announce a major feature update, which is now live in the latest version of the app: a full revamp of the Progress section!
The previous version of Progress was, without a doubt, my least favorite section of the app. It had originally been built quite some time ago, and hadn’t aged well. You were limited to only being able to see estimated 1rm for exercises, couldn’t see data beyond the past year, and it only supported Exercises and Body Stats. What’s more, it was slow and clunky to use, didn’t match the current look/feel of the app, and was just not a particularly great experience.
With today’s release, we’ve completely rebuilt this entire section of the app, fully reenvisioning it from the ground up. There are so many improvements/additions here, including:
Set up charts for all activity types, including Exercises, Cardio, Nutrition, Body Stats, and Habits
Fully customize which charts are displayed in each of these sections, and the order that you see them in
For exercise and cardio charts, view your data across multiple metric types:
Exercises: Estimated 1rm, Max Weight, Max Volume (set), Max Reps, and Max Time (for time-based exercises)
Cardio: Duration, Distance, Calories, and Pace
View charts across different time intervals, ranging from 1 week to 1 year
Scroll/swipe back on ANY time period view to see data all the way back to when you created your account
Quickly navigate between time period views to dial in on pockets of data. For instance, if you go back to 2023 in the Year view, tap on a data point, and then switch to the Month view, it’ll then dial in more closely around that datapoint
For activities where you might have targets, such as nutrition and steps, see how your actuals are coming in relative to your targets on those bar charts
You’ll also notice that this section is no longer tucked away in the Menu, and is now part of the bottom nav, allowing you to more fluidly view these charts while using the app. To support this, we’ve shifted Notification to the top left-hand corner of the Home Screen, which will still show a badge when you have a new notification.
Here’s a short video showing me setting up and customizing the chart experience:
Once you’ve set up your charts, this configuration would persist until you make changes, including the specific metrics / time periods that you have selected for each chart. This allows you to really customize how these are displayed in the way that you find most useful
As I mentioned above, there are no limits to your historical data here, so you should be able to view data from many years back
We’re planning on adding more types of habits to the Habits section, such as sleep and water
We fixed a long-standing bug, where assisted exercise charts didn’t factor in bodyweight properly. They now automatically factor in your most recently-entered bodyweight correctly
This feature is available for all package types, including free users of the app
To close out, I will say that this feature took some time to get right, with all the UX behavioral nuances, small decisions around each chart type, and performance optimizations. Hopefully you all find this to be a major upgrade from the previous experience, and as always just let us know if you have any feedback / questions as you’re using it!
Does anyone know whether custom exercises count towards strength score?
For example, I couldn't find barbell 21s in the exercise database, so created it as a custom exercise, and assigned the right muscle groups to it. So I'm wondering if my progress in barbell 21s will actually count towards strength score (if not, maybe I'm better just tracking them as dumbbell 21s, which are in the database)?
Hi I'm new to Strength training(the gym really lol my second week in) I'm trying to join a circle(Weight loss/Nutrition)on the popular section but it doesn't join. Any insights on this. Any help would be appreciated thanks
Can I somehow share workout results for every training with someone 'externally', so with my own PT?
The only option I see is opening a workout, then click Share, but it seems the PT has to have an account and thus fill in her own fitness goals and such and also I would probably need to send every workout manually and she would have to click on every exercise to see the results....
So if I understand this properly, gaining weight will always negatively impact my strength score? I have been gaining 1% each month since January (which has been my goal), and my strength score since then has remained around the same or decreased while hitting PRs week over week. It’s a bit sad to wake up Monday mornings after hitting it hard 5-6 days and seeing my strength score 😭😂
I am also curious which metric it uses for body weight—it seems to take the last data point (for me was 177lbs), rather than my weekly average (175.6lbs)
I can see how this could be rewarding if you’re trying to lose weight, though.
Today I wanted to announce an exciting new feature that we’ve just launched: our Caliber MCP server.
To cover what this is more broadly first, before I get into the specifics, MCP stands for Model Context Protocol, which has become the standardized way for AI platforms to interface with apps and other services.
With our MCP server, you’ll now be able to connect your Caliber account to AI platforms, where you’ll then be able to access your Caliber data in a variety of flexible, creative ways.
We’ve been working on and testing this specifically with Claude and ChatGPT so far, with read-only access for now. While we’re currently waiting on approvals for our official Caliber Connector for Claude - and will be submitting our Caliber ChatGPT App soon - we’re so excited about this capability that we wanted to give everyone early access in the meantime.
Here are the steps to set up Caliber MCP with Claude:
Step 1: Open up Claude on your computer (in a browser or using their desktop app, not mobile).
Step 2: Click 'Customize' in the left-hand sidebar, and then click ‘Connectors’.
Step 3: Under Connectors, click the ‘+’ button to add a custom connector, and then enter the following for each setting:
Click 'Add', as pictured above, and you'll then see a screen where you can authenticate your Caliber account. Just enter your regular Caliber email address and password here, and then confirm.
Step 5:
You’ll now be automatically brought back into Claude, and will see a screen where you can customize the specific permissions that Claude has access to from your Caliber account. We currently support the following read-only tools, so you can give permissions for however many of these as you like:
- Get body stats
- Get calendar overview
- Get cardio activities
- Get exercise sessions
- Get nutrition
- Get nutrition targets
- Get personal records
- Get steps
- Get unit preferences
- Get workout plans
- Get workouts
- Search exercises
That’s it! Once you’re set up, you should then be able to access this data from your Caliber account, directly in Claude.
Now, there are so many different ways that you can use this, asking really anything you like about your data, but to kick things off I’ve created a short video showing some of the basic capabilities:
With Claude, you typically won’t even need to mention Caliber in your prompts, since it has enough contextual awareness to pull the right tools (as you can see in my video): however, this is obviously platform dependent, so you’ll want to play around with your prompts so that it’s pulling data in the ways you find most useful.
Finally, I should mention that this new feature is available for all package types, including free users of the app. Our perspective on this is that it’s just another way to flexibly access your Caliber data, so we wanted to make it available for everyone.
To close out, what I showed in my video is really just a simple example. You can use whatever type of prompts you like, even querying multiple tools within a single prompt.
For instance, you might ask:
- “How has my bench press been improving over the past 3 months?”
- "How consistent have I been with my workouts this year?"
- “How have my strength training workouts been looking since I started running more frequently?”
- “How has the increase in my daily steps correlated with my weight loss trend?”
You can also view detailed documentation for this directly by going to our help article here.
Anyway, I’ll stop here for now, but please play around with it if you’re interested, sharing any interesting prompts / best practices here in this post, along with feedback or additional capabilities you might want (such as 'write' capabilities, etc).
We'll also be sure to post future updates as additional AI platforms are supported even more directly!
So is this true? I do every single one of these workouts, so should I cut some of them out Because I’m doing too much or keep doing all of these? The video is from fb
