whenever i do cardio right after i get off the treadmill if i extend either of my calf muscles they cramp severely and also my inner thighs do the same thing. also whenever i do calves on leg day no matter how light or how much i warm up they always feel like i pulled them and they hurt like hell for a few days. i have no idea why this is going on but my calves are terrible looking and im getting fat because of it, in my first couple years of lifting i never had these problems. whats going on? and how can i fix this?
