Description

Add more weight to your LaceUp gear with a single FLX Weight insert. Flexible, safe, and comfortable — this is weight training the smart way.

Why FLX Weights beat traditional weights:

Flexes with your body — Bends and moves naturally as you exercise, instead of fighting against you.
Soft, safe protection — As soft as your own skin, it doubles as padding if you take a fall.
No sharp edges — Fully rounded corners mean no hard bulges, pinch points, or pressure spots.
Safer than the alternatives:
- Metal bars can shift dangerously during a fall and restrict movement, making them unsuitable for floor exercises.
- Shot bags and sand bags bulge and shift, causing chafing and bruising — also not floor-exercise friendly.

Specs:

½ inch thick, 2 inches wide, 4 ½ inches long
