Resistance bands recruit the 'stabilizer' muscles – this muscle group is significant because it supports our larger muscles and joints when we move, and helps reduce the risk of injury. So they are a safe and low-impact option for older people, and are often used for rehabilitation.
Using these elastic or fabric bands to add tension or resistance during exercise makes it more difficult to do movements, and engages more muscles, which helps to build strength.
Resistance bands are portable and incredibly versatile, so they are great for all different fitness levels from beginners to pro athletes.
You can do a full-body workout with them and, as with all strength training, they help to build muscle mass and tone. Resistance bands workouts also strengthen the back, shoulders and core muscles, which can improve posture and stability.
Musclemania Fitness Megastore has a very comprehensive range of all types of strength/exercise/resistance bands, loops, booty bands, flat bands and sets.
