The Truth on Fitness: Should I Wobble While I’m Exercising?

Cybex Research InstituteOne of the most popular trends in fitness centers is exercise on physioballs, balance boards, tilt disks, foam rollers and pads, inflated rubber disks, and Bosu’s™, collectively thought of as unstable surfaces. The rationale behind this approach is that the inconsistent motion increases muscle activity, leading to enhanced joint stability, balance, and functional strength.

But while patients with chronic joint instability have benefitted from unstable training, normal healthy individuals seeking real strength and power improvements have not.

In fact, several different research studies have revealed that training on unstable surfaces reduces overall force output and rate of tension development by as much as 70%.  A recent study demonstrated that performing deadlifts on unstable surfaces produced lower levels of muscle activation and less force output than doing the same exercises on solid ground.
