Mini-Bands can be used anywhere – on the field, at home, in the clinic or gym, or even when traveling. Effective for both upper and lower body training. By using resistance bands for dynamic warmup, you can target the hip and shoulder complexes. When used in conjunction with other exercises these band sequences can help activate the core as well as prime movers, synergists and stabilizers in the hip and shoulder area. Mini Exercise Bands come in Singles, Sets of 4 or Sets of 10, the 4 different colors reflect the following resistances; Yellow is light resistance, green is medium resistance, Blue is Heavy resistance and Black is Extra-Heavy resistance. Exercisers can choose between different resistance levels that will best suit their workout. They can be easily carried around. You can use them at home, at work or during travel.
