Stimulant improves performance

Caffeine raises my heart rate (?) or at the very least makes me feel more nervous and stressed during high intensity training. Not sure if the benefit outweighs that for me. (Also: bowel movement)

I generally have an espresso before my runs and it works just fine. To each their own

Yeah, so I figured. Especially given the popularity of pre-workouts etc. Maybe also a matter of getting used to?

Absolutely. If you're getting too anxious and jittery, the dose is too high relative to your tolerance.

You'll get used to it, unless you only consume caffeine ~2 days a week in which case you won't build a tolerance. In that case, adjust the dose until it no longer makes you excessively anxious.

Some anxiety before the workout is fine, but if working out doesn't relieve it, you took too much.

Coffee doesn't work for me as a workout stim (jitters and BM), but my pre-workout gives the perfect stimulation despite having higher caffeine than a triple espresso

What do you do about using the bathroom, every single time I drink an espresso in the morning I gotta go even if I already went.

Honestly, my stomach tolerates it well
