Hi: Where do I go to purchase the Tower as I have not seen it on ShopCathe.com. Thanks.
""I have also heard of laying a barbell or wooden dowell securely across two sturdy chairs, laying beneath the bar with your chest directly below the bar, placing your
hands on the bar in an overhand grip. Bend your knees and place your feet on the ground.
Then, pulling your chest and torso up toward the bar, and then slowly releasing back down to the start position.
