A push-up is a moving plank. The moment your torso stops working as one unit, the exercise changes — and usually gets easier in a way that shortchanges you.
The usual suspects
- Hips sagging (loss of the plank line)
- Flaring elbows to 90° from the torso
- Half reps — not reaching a full bottom
- Head craning forward
- Speeding up as fatigue hits
OurFit scopes each of these to the right phase of the rep, so you're not penalized for the natural shape of the movement — only for the actual fault.
