DESC: For goal-oriented training, the Proform 21.1T Assisted Power Tower has a dip station for dips and pull-ups and a pad that easily folds down and out of your way. Tone your oblique and hip flexor muscles, lose inches around your waist, and develop abdominal muscles worthy of showing off with the vertical knee raise station with fold-away arms. Make sure to get the most out of your push-up workout with the multi-position hand grips.
