To perform the tibialis raise, I initially used the awesome tibialis machine by Hammer Strength. Unfortunately, I must've been the only guy at my gym that actually liked it because the owner got rid of the machine halfway through my experiment. (Maybe a weak-calved competitor of mine paid him off?)
After that happened, I initially just said to heck with it and quit doing the tibialis work, and before long, my calves shrank back to normal! So I knew I had to find a way to perform the exercise.
Fortunately, while cruising the T Nation forums, I happened upon a kid who said to do them using a band. I tried it the next day and it worked great, and before long my calves were back up to their new size again.
