Grasp high suspension handles.
Pull body up until neck reaches height of hands. Lower body until arms and shoulders are fully extended. Repeat.
This exercise can be performed on adjustable length gymnastics rings or a dual anchored suspension trainer where the handles can be placed a short distance apart. Performing this exercise on a TRXⓇ style suspension trainer would require a narrower grip, with the hands closer together.
Decrease difficulty by placing feet on bench or floor under bar for self assistance.
Added weight can be placed on dip belt or dumbbell can be placed between ankles to increase intensity. Also consider pulling body up over handles.
