Wide Grip
As the longest bow, the Bow Classic® gives you the equivalent range of a wide grip while hitting bench presses, pull-ups, lat pulldowns, or push-ups. With the wider grip, you are working a greater range of the targeted muscle so that you can build muscle fast.

Isometric Holds
Scientific studies have shown that isometrics are highly effective at building strength, in part due to the time your muscles are under tension (TUT) during an isometric hold. Nothing delivers results like muscular time under tension and isometric holds.

Upgrade from my 40yr old version. Much better feel with rotating handles and ability to change resistance springs ISO-BOW great for maintenance whilst travelling. ISO-FLO upgrades and adds to exercises with bullworker whilst also enabling suspension workouts for total body and cardio fitness.
I have all I need for all my training requirements without need to spend time travelling to the gym
very good
I’ve had the Pro System for about a month now, and every piece of equipment has impressed me with how effective they are. This really has been the only non-weight-based strength training equipment I’ve used that really feels like you’ve worked out when you’re done. I wish I’d gotten Bullworker equipment years ago!
I can' t say enough about how bullworker classic, the Steel bow and the extensions have helped my health and fitness. Quality products and a Quality company. There is a reason the Bullworker has past the test of time.
