The Valor Fitness BD-3 Squat Stands are adjustable to fit each person's height. Squat stands are great for someone looking to use light weight and multiple reps to tone muscle. These stands are not for anyone planning on power lifting. The H desighned bases allow a stable stance while in use. Spotter bars are included for emergencies. Rubber end caps provide protection for your floor and stability. Logic and common sense needs to be understood when raising the bar supports to a higher position while also adding more weight. The leverage support factor is not in your favor the taller the posts are raised along with more weight being added.
