Set the safety bars to the height that will give you enough resistance to do 10 chin ups (palms facing in). Stretch the band so that is attaches to both safety bars. Step on and start your chin ups! You can increase the resistance by lowering the band or using a thinner resistance band. We do this as part of our warm up. Coach David Alexander
