To do these exercises you will need dumbbells. The most important in these exercises is your knee should be in the same plane with your foot so you'd better make a short step and do not bend your knee too much.
So let's get it started.
Take a dumbbell in every hand and put your feet together. Make a step aside with your left leg, bend your left knee and bend your body forward touching the floor with both dumbbells. Then do the same with your right leg.
You hold your dumbbells in your hands, stand with your feet together. Make a step backward. Turn your foot and your body back, bend and touch the floor with your dumbbells, recover your place. Do the same with another leg.
Put your feet together again and make a step forward, bend your body and touch the floor with the dumbbells, then change your leg
