That seems to bear out what I felt.
I also had a slight amount of pain in my hips the day after the calf raise. This is because the hips are trying to stabilize the body.
Now this is supposed to be dangerous. However what occured to me was that we could actually strengthen this stabilizing ability. Does anyone know if there is any value to this?
Another issue is if we can generate more force with one limb then would this be a legitimate of increasing intensity? Would we create a better stimulation?
I suspect that the limitation is an electrical one. By that I mean that the brain can only send out somany impulses. If it has to divide them between two limbs then the force goes down.
Could this be an additional reason as to why isolation exercises cause more inroad?
