> 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.
Fair enough. I'm guilty of skimming the article, but I saw this: "The soleus pushup looks simple from the outside, but sometimes what we see with our naked eye isn't the whole story. It’s a very specific movement that right now requires wearable technology and experience to optimize the health benefits”, and some statements that made it sound like something requiring specific tech not available to the public.
Thank you, gotta say with that description of the move now it doesn't sound that hard.
from looking at pics of the gastrocnemius muscle (at the back of the lower leg, main portion from the knee, ending about midway down the lower leg, attaches to the achilles tendon) and the soleus muscle (underneath the gastrocnemius, extending from the knee down to the ankle), the gastrocnemius shouldn't activate during the motion.
It seems like you could put your hand on the back of your calf, close to the knee, and ensure that the gastrocnemius doesn't flex/stays loose during the motion.
Seems like a trailer for something that needs to be unlocked with money.
