No home gym is complete without hex dumbbells—and you can save 20% on the best weight for beginners in the Amazon Prime Day sale

Ever since I started picking up dumbbells in my youth, rubber-headed, hex-shaped dumbbells have been the gold standard.

But don’t just take my word for it. Leading trainers for top CrossFit athletes and Hollywood actors swear by hex dumbbells too.

A set of 25lb hex dumbbells should serve as a good starting point for any beginner: light enough for upper-body exercises while heavy enough to challenge the larger, stronger lower-body muscles. It’s all you need to tackle this four-week beginner workout plan.

And now is the time to strike if you’re looking to upgrade your home gym.

Why I recommend hex dumbbells

Hex dumbbells nail the three attributes I look for in dumbbells, whether working out at home or in the gym. They are robust, stable and offer ample grip without ripping your palms apart.

The hexagonal shape ensures the weights stay put for floor-based exercises like renegade rows and weighted burpees, and won’t roll away like round-headed alternatives.

The rubber padding will protect your floor—or toes—from regular use, and won’t crack or chip either.

And the slightly knurled and convex design of the handle, I’ve found, sits comfortably in the hand no matter if it’s your first rep or 50th.
