calves are actually an easy place to store fat so if you lose fat on the legs, they're bound to improve in definition, for sure and if you've got a good genetic base, then you're laughing.
For the rest of us slender young things
, it's a little tougher to build 'em up.
Trying something different to "shock" the calves isn't a bad idea. Works well for other things, once there's been too much adaptation.
I'd probably stick to around 12-15 reps done slowly on the way down. That's a killer.
and lol i can't help it ...
