Trying to figure out the weight room changes. The company they went with seems to go deep with how they use the equipment/train.
In one video there is a segment of prepping with Vitamin C and Gelatin(tendons) one hour before working out to help strengthen tendons. Apparently tendons do not have not much vascular structure, but when you load them, some of the liquid in them gets squeezed out. And when you unload them, the liquid returns. If your body is loaded with C and gelatin, some Gelatin makes it back into the tendon and the tendon gets stronger.
This is really important for avoiding tendon tears and overuse injuries. For me tendons are the limiting element in training and when ripped, they take a long time to heal.
