keep your back straight.
Execution
Bend your knees until your thighs are slightly below
horizontal. In the process, shift your buttocks backward.
Brieɻy hold the ending position, tense your leg muscles at
full strength, and breathe evenly. Next, stretch your legs
and raise your heels at the end of the movement. Make
sure that your knees remain above your feet and don’t
move to the front or side. Then do a repetition.
Variants
Beginners should do the exercise with a limited range of
motion or without a weight. You can vary the weight by
holding the punching bag on your shoulder or by using
dumbbells.
