Color codes and levels of resistance of the elastic bands. One RM (one-repetition maximum) is the maximum load/resistance that an individual can lift just once with proper technique in the entire range of motion of the exercise. Top row: 1 repetition on each level until 1 RM is found. First column on the right (marked with red): Tick the intensities closest to 40, 60, and 80% (highlighted in gray in main table). Second column on the right (marked with red): Number of performed repetitions on each of the 3 levels to exhaustion. * Resistance in Newtons at 100% stretch length of the elastic band.
