Microloading with PlateMate® is the safe, scientific way to build strength at beginning, intermediate and advanced exercise levels. Microloading with PlateMates is essential at all levels. Beginners are apt to do exercises properly and avoid injury. Intermediates stay motivated because they experience steady progress. Advanced lifters benefit because microloading helps them break through "the plateau" to achieve success at the highest levels of weight training. PlateMate donuts fit securely over the ends of pro-style dumbbells. PlateMates are also versatile. These magnetic add-on weights attach quickly and easily to ends of any iron dumbbells, Olympic bars, and stack weight machine plates. PlateMates are ideal for physical therapy where small increases help patients regain strength without overburdening injured muscles and tendons.
