Loading your body with small amounts of distributed weight can help you build strength, power and endurance.



Loading your body with small amounts of distributed weight can help you build strength, power and endurance.

How it works

The principles behind MicroLoad are simple:

  • By placing weight on the parts of the body that are moving, you increase the challenge to the active muscles.
  • By keeping the weight light, you can move with nearly the same speed and intensity.
  • By distributing the weight across your body, there is no interference to how you move naturally.

What this means:

This means you can increase the effectiveness of your training and realize greater results, without changing anything but what you wear.
