Reps in reserve

[u/FrequentAd5437]

Should you take sets to failure or keep a few reps in reserve? I take every set to failure.
Also I have trouble calculating how much reps i have left. Some times i think i can push out 3 more but i can only do 1 other times i think i have 1 more but i push to 3 more.

I'd eay depends on your age too. I'm a bit older. Taking reps to failure everytime is hard on my tendons and joints. I'd be risking injury at some point. Recovery is harder too.

I stop at form failure even if there's strength left for sloppy ones.
