Chin-Up: Are you flailing your legs as you pull up?
Keep your legs still and bend your elbows to pull your body up. Do not flail your legs.
How to fix it
- Grip the bar with your palms facing you.
- Keep your legs still as you go up, without swinging or kicking them.
- From a hanging position, bend your elbows to pull your body up toward the bar.
Caution Do not drop down suddenly.
The app sets the reps for your next set
For example, if you completed all your sets as planned in your last workout, the app sets your next reps based on that record. When you log your sets, GYMKC reads your last set and recalculates the weight and reps for your next set.

How high should you go?
Sources use slightly different guidelines. Some suggest going up until your chin clears the bar. Others suggest going up until your chin is level with the bar or your hands. Either way, keep your legs still as you go up.
