Calf Strength
Each time we land when running the calf has to absorb 2-3x your bodyweight. The calf complex also provides up to 60% of our shock absorption when walking/running!
Having big, strong calves is a necessity to prevent injuries and improve performance especially for runners and those playing high impact sports such as netball, soccer and AFL.
Give this simple test a try and see how you go compared to normal values for your age bracket.
