What you are doing wrong: you get started by keeping your knees bent.
How to correct your form:
– According to Dan John, you need to try to sit back between your legs. Start this move by moving your hips backwards.It is dangerous if you bend your knees first because more pressure will be put on your joints.
– According to Charlie Weingroff, you need to use your imagination to think that you are stepping on a towel and trying to rip it apart by pushing your feet against the floor. This way, your glutes will be activated, allowing you to use more weights.
– According to Alwyn Cosgrove, C.S.C.S., you should try to think that you are pushing yourself away from the floor, not raising your body. You will be able to engage your legs muscles better.
How to do it right: a correct form is what necessary to get the most out of your workout.
