Training in unstable environments forces you to concentrate and uses more of the muscles in the body to execute. It corrects muscle imbalances, improves stablization or the core, it prepares tissue for upcoming demands of training, improves cardiorespiratory and neuromuscular systems and establishes proper movement.
Do unstable training for at least 4 - 6 weeks to see the increase in body fat reduction, strength in the stabilizing muscles, lean muscle mass and general performance. Here are some examples of unstable exercises:
Bosu Ball Squats
Bosu Dumbbell Reverse Lunge with Knee Lift
Bosu Goblet Squats
Bosu Ball One Leg Bridge
Bosu Split Lunges
Bosu Stiff-Leg Deadlift
Swiss Ball Leg Curls
