Just Found
I just found this gold nugget of information.
"Since muscles which go through growth in size but not in length, when one muscle grows through hypertrophy its opposite side muscle (the antagonist) will have to lengthen, and absolute flexibility is the term to describe a muscle's length, in and of itself, where relative flexibility is the flexibility of a joint, as compared to its antagonistic movement[1]."
"For example, the calf muscle extends the foot towards the ground (plantarflexion) and the shin muscle flexes the foot in the opposite direction (dorsiflexion). If a person's calf is overly strong it will not be as flexible as the opposite shin muscle, and plantarflexion will be exhibit relatively inflexible as compared to dorsiflexion using the person's weaker, but more flexible shin muscle."
So as I've been strengthening the calf muscles, I've been increasing the likelihood of plantar fasciitis. I either have to increase the strength of the shin, or reduce the strength work of the calves.
