Sounds amazing at a first glance, but I was hoping to at least see them attempt to describe how the move is performed. Seems like a trailer for something that needs to be unlocked with money.
> In brief, while seated with feet flat on the floor and muscles relaxed, the heel rises while the front of the foot stays put. When the heel gets to the top of its range of motion, the foot is passively released to come back down. The aim is to simultaneously shorten the calf muscle while the soleus is naturally activated by its motor neurons.
Thank you, gotta say with that description of the move now it doesn't sound that hard.
