I love introducing this one to my clients- they all look at me like "wow that looks easy" and then as they do about 8-10 it starts to burn!
Fairly simple exercise:
1. Grab a weight (or no weight for beginner) in both hands. Hold the weight to your chest. (Alternatively- if you have bands as shown in the picture, feel free to use those, rather than holding a weight).
2. Bend the knees into a semi squat position. Keep the tummy tight, chest up.
3. Without allowing your weight to come up, take large steps laterally (about 10-12).
4. At the other end stand up straight, stretch the legs, and return!
