Our verdict

A pair of neoprene wrist weights that lock around the thumb to resist sliding during walking and workouts. The weight is fixed, so progression means buying another set.

Overview

A walking route or home workout gets extra upper-body load from these wrist weights, which wrap on with a hook and loop strap. A thumb lock anchors each weight so it does not creep, and a fabric pull tab helps with removal.

The thumb lock addresses the usual wrist weight complaint of slipping while the arms move. Neoprene adds comfort against the skin. The limitation is a fixed weight per cuff, and the listing gives no strap length or wrist size range.

Who it's for

Light cardio and toning sessions where the arms move through a normal range. Because the weight per cuff is fixed, lifters who want to build load over time will outgrow them. They are wrist weights only, so ankle work needs a different product.

Pros and cons

Pros
  • Thumb lock resists slipping
  • Neoprene wrist contact
  • Easy-grip pull tab
  • Hook and loop closure
Cons
  • Fixed weight, not adjustable
  • Wrist size range not listed
  • Wrist use only, not ankles

Performance notes

Added mass at the wrist raises the effort of each arm swing, which is where the extra work comes from during walking or light workouts. The thumb lock stops the cuff rotating around the wrist, and the hook and loop strap sets how snug the cuff is. Fixed weight means the load does not change between sessions.
