Let me start by saying this slingshot is NOT just a fancy rubber band. After struggling with nagging shoulder pain during bench presses (sound familiar?), the Reactive Sling Shot became my secret weapon. My first session? Hit 255lbs when my max was 240lbs - with ZERO shoulder discomfort. The magic happens at that vulnerable stretched position where it subtly offloads stress while reinforcing perfect form.

The Level 2 tension strikes a perfect balance - supportive enough for heavy lifts yet flexible for speed work. I've used it for bench presses (obviously), but where it surprised me was during weighted dips. That moment when you're at the bottom position? The slingshot gives just enough assistance to maintain control without robbing you of gains.

Fit is CRUCIAL - I'm 5'11", 180lbs lean, and the XL fits snugly above my elbows. Pro tip: If you have developed triceps, size up! The first time I tried a Large, it felt like a blood pressure cuff mid-set. The XL stays put without restricting circulation.

What nobody tells you? This thing TEACHES proper pressing mechanics. After two months using it for my first working sets, my raw bench form improved dramatically - no more shoulder shrugging or elbow flare. Now I can hit 225lbs x5 clean reps without the band - something impossible before due to shoulder strain.

The durability shocked me. After six months of abuse (including some outdoor workouts), zero signs of wear. Unlike cheap knockoffs that slide down your arms, Mark Bell's design stays locked in place through grueling sets.

Is it worth $50? If shoulder pain limits your pressing or you want to safely overload lockout strength - absolutely. Just manage expectations: It's not a miracle worker for terrible form, but when used correctly, it's like having an intelligent spotter that only helps exactly when needed.
