If your calves need some new growth, nothing beats the donkey calf raise. The old-school bodybuilders did them with a training partner (or two) on their backs. Then donkey calf raise machines came along. And many people still do them today using a dipping belt.
While those variations are effective, they have a lot of drawbacks. Let's go over the pros and cons first, then I'll show you a new, practically way of doing them.
To get all the calf-building benefits without the problems, try angled barbell donkey calf raises. This exercise allows you to go as heavy as you want without partners, a special machine, or shins injuries.
Have fun walking funny for couple of days and enjoy bigger calves!
