REVERSE LUNGE TO PLYO JUMP

(a) From standing, take a big step back on your right leg and lower into a lunge, so that both knees are bent at 90° and your back is straight.

(b) Now, driving through your left heel, draw your right leg up into a high knee and hop on your left leg as you swing your left arm forward. Land softly back in your lunge. Do your 30 reps, then switch legs.
