Hanging Leg Raises
Hanging leg raisees should be a staple exercise in your calisthenics program. A lot of calisthenics movements require strength gained in this movement. These are also great exercises for building muscle in your abdominals. Depending on you strength there are two different ways to perform this exericse. The first is with bent legs and the second is with straight legs.
Bent legs are easier than straight legs. So if you are a beginner we would recommend using bent legs. If you are intermediate-advanced use straight legs
Grab a bar about shoulder width apart and hang from it. Bring your legs up until legs are parallel with the ground and then back down.
