Bowers are an advanced pushup variation that I use quite a bit with my stronger athletes. It is very similar to a hollow back press handstand; however in a hollow back there is generally an upright support phase (L-sit or straight body support) at the end of the repetition, while in a Bower the bottom support phase is a bent arm planche. This change in the bottom support position significantly increases the time under tension for this movement, which in turn results in accelerated strength gains
