Having strong shoulders isn’t just about looking good (though, let’s be honest, it’s a nice bonus). Strong shoulders mean fewer injuries, better mobility, and the power to hoist heavy grocery bags like a champ.
So, let’s talk about how to get there with the Shoulder Boulder/Chest Fly Attachment from Bells of Steel.
Let's get into it!
Why the Shoulder Boulder/Chest Fly Attachment Rocks
Traditional shoulder exercises can be tricky. Dumbbells don’t always provide the right resistance curve, and cables can feel inconsistent. The Shoulder Boulder/Chest Fly Attachment changes the game by offering a smoother, more controlled way to hit your shoulders from every angle.
Why You’ll Love It:
- Lightweight & Adjustable: Attaches easily to your rack, with height adjustments to match your perfect lifting position.
- Swivelling Arms: Move naturally with your body, so you’re not fighting against awkward positioning.
- Plate-Loaded System: Use your own weight plates to fine-tune resistance and make small, controlled progress.
- Smooth Resistance Curve: Keeps tension steady throughout your lifts for better activation and less strain.
Shoulder Exercises You’ve Gotta Try
1. Side Raises
Set the attachment high and feel your lateral delts come to life. Unlike dumbbells, this setup keeps constant tension throughout the movement, making your shoulders work harder.
2. Pec Flys
Dumbbell flys often lose resistance at the top, but the Shoulder Boulder keeps the tension steady for a deeper muscle squeeze and a stronger chest pump.
3. Rear Delt Flies
Pair it with a Seal Row Pad, and you’ve got the perfect setup for rear delt work. This angle ensures your often-overlooked rear delts get the love they deserve.
4. Front Raises
Adjust the height and let your anterior delts do the work. Since there’s no momentum to cheat with, every rep is pure muscle engagement.
Will It Work With Your Rack?
The Shoulder Boulder/Chest Fly Attachment is designed to fit Hydra and Manticore racks, but it’s also compatible with most non-Bells of Steel racks that have 3” wide uprights and ⅝” holes. And of course, always secure your plates and rack—because unexpected flying weights are never part of the workout plan.
Final Thoughts
If you’re serious about building cannonball delts and upgrading your upper body training, this attachment is a must-have. It’s versatile, safe, and flat-out more effective than traditional dumbbells or cables.
