Coaches and athletes use different resistance exercise regimes to affect their muscle mass and strength.  Unilateral resistance exercises are often chosen to specifically target an area to improve performance. It is also common to use unilateral exercises to provide for recovery during the rehabilitation process.

Training with a single limb requires more muscle groups to be involved in stabilization and enhanced motor unit activation to decree more specific strength gains. Reducing the between limb asymmetry allows for greater enhancement of applying force bilaterally.

Rhythmic arm and leg movement during human locomotion is sought after in athletics. Training a single limb periodically is important in optimizing excellence.
