Perfect For
Used By
From kids to senior citizens, they are the bands of choice for resistance training, chiropractics, and physical therapy, providing positive and negative force on the joints, muscles, and tendons.
- Personal trainers
- Home gym owners
- Middle schools and up
- Professional athletes
- Yoga and Pilates studios — used to stretch, strengthen, and tone
Uses Include
Hip adduction, kick backs, reverse lunges, push ups, crunches, rehab movements from injuries like knee surgery, bicep reattachment, rotator cuff surgery, stretching calves, hamstrings, foot and ankle mobility, bicep curls, rows, triceps extensions, press, and more.
Not Just For Physical Therapy
Engage muscles you never knew you had by adding the plates into your current workout.
Example: Take barbell curls to a new level. Add 0.5kg or 1kg plates when 2.5kg jumps are too much. Your muscles recruit more stabilizer muscles you do not usually use to control the weight. Muscles are forced to keep constant tension.
- No longer have to concentrate on the squeeze — the weight forces it automatically
- Extra tension in small increments forces you to stabilize your body, forcing cleaner form
