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. Includes: Set of 4 bands. Yellow - Light Resistance. Green - Medium Resistance. Blue - Heavy Resistance. Black - Extra Heavy Resistance and Exercise Manual.
