You asked for heavier Micro Bands, so here they are! Micro Bands are essentially Power Bands which are smaller in diameter thickness. Because of their size, shape and resistance they are well-suited to rehabilitation, prehab and activation drills. - Our Micro Band Elites are made of woven fabric & rubber, resulting in a band that is more gentle on the skin and hair and virtually unbreakable. - Great for prehab exercises like monster walks, where the band is looped around the ankles and you crab-walk sideways, are an excellent activation exercise for the gluteal muscles. Finally, Micro Band Elites are an excellent way to teach formal cues, especially for an exercise like squatting. A common error when squatting is valgus collapse, or the knees coming together as the person descends. By looping a Micro Band Elite around the legs just above the knees, it forces the squatter to keep the Band under tension by pushing the knees out forcing the correct muscle to fire. These Elite Micro Bands will satisfy even the strongest of lifters. - Virtually unbreakable and resistant to tearing - Won’t roll up - Longer lasting than current Rubber Bands Lachlan Wilmot Head of Athletic Performance at Parramatta National Rugby League Club - Note:Micro Band Elites are only made to be stretched 2.5 times their resting length. Any further stretch may cause the bands to deteriorate at a faster rate. If you are able to stretch a Micro Band Elite's past 2.5 times resting length it means you are ready to move up in resistance, please select a heavier band
