Bring your knees up to waist level. Keep a slow, steady pace

Bring your knee up to waist level and raise the opposite arm up. Do a small hop to transition to the other side (other knee up, other arm up).

For low impact modification; put both leg and arm down first, then repeat motion on the other side.

Laterally raise your arms so they are parallel to the floor. Make small circles clock-wise with your arms. About half-way, reverse and go counter-clockwise.

Stand with feet a little wider than should width apart. Laterally raise your arms so they are parallel to the floor. Laterally lunge to your left and cross your arms in front. Return to starting position. Repeat other side.

Stand with feet shoulder width apart and place your hands behind your ears. Bring your left knee and your right elbow together, slowly crunching your core. Reset to starting position and repeat other side.

Do a standard forward lunch with arms out-stretched in front of your. When you reach the end of the forward lunge, twist your core to the same side that your front leg is (if your left leg is in front, twist to the left). Repeat other side.

Bring your feet wider than shoulder width apart. Sit in a 'sumo' position squat. Proceed to do calf-raises in this position.

Stand straight up, feet about shoulder width apart, arms at your side. Do a small hop to bring your right leg and left arm forward with your left leg and right arm back (see gif for positioning). Hop to switch to other side.

For lower impact, just step your left leg and right arm forward. Reset to starting position. Repeat other side.
