Exercises.
The exercise library, demos, and substitutions.
Where do I see how to perform an exercise? +
The Technique tab inside a workout, or Profile → Exercises for the full library.
Why did CheckFit pick these exercises? +
Every movement in the library is ranked for stimulus versus fatigue, and each one in your program has a written reason — open the exercise and read Why This Lift.
Can I replace an exercise I hate? +
Yes — Replace Exercise in the workout menu. Rate an exercise poorly for joint stress and CheckFit will suggest replacing it on its own.
What do the body illustrations show? +
The muscles the exercise targets. It's a map, not decoration — check it when you're not sure what a lift is for.
What does e1RM mean on the Stats tab? +
Estimated one-rep max, computed from your weight and reps. It's the cleanest single number for tracking strength on a lift across rep ranges.
Can I request an exercise you don't have? +
Email hello@checkfit.com — the library grows from exactly these requests.
Does CheckFit support supersets? +
Not as a formal structure yet. You can log any two exercises back to back — the tabs make switching quick.
Why does an exercise show a suggested starting weight? +
For lifts you've logged, it's your history. For new ones, CheckFit estimates a starting point from your profile and the lifts it has seen you do — expect it to be close, then correct it once.
