This move requires a special type of tree. Find a tree with exposed roots or strong horizontal branches that are low to the ground. It should also be relatively level, but it doesn’t have to be perfect. With your back facing the roots or horizontal branch, place your hands down on the tree about shoulder-width apart. The fingertips should be going towards the hips, or slightly angled out. Either have the knees bent and the feet down, or have the legs fully extended with just the heels down (which is more challenging). Shift the body forward slightly, and keep the hips lifted the entire time. On an inhalation, bend the elbows and lower the body down. On an exhalation, press back up to the starting position — using the triceps. Keep the arms tucked in close to the body, as opposed to flaring the elbows out. For an extreme challenge, you can also practice this move with the gymnastics rings hanging from a strong branch. Please do not attempt this move with the gymnastics rings unless you have a high level of fitness. You should be able to do at least 30 push-ups in a row and at least 10 pull-ups in a row.
