Aquamentor Medium Resistance Water Dumbbells (Pair of 2)

Aquamentor Medium Resistance Water Dumbbells – Aquatic Fitness Tool (Pair of 2)

Aquamentor Medium Resistance Water Dumbbells are the versatile entry point into water dumbbell training — providing meaningful buoyancy resistance for aquatic fitness participants who are new to water exercise or working at moderate intensity. The closed-cell foam construction pushes back against submersion movements, creating resistance for arm curls, overhead presses, lateral raises, and the full range of aquatic fitness upper body exercises without any joint impact.

The Everyday Aquatic Fitness Dumbbell

Medium resistance is the right starting point for most adult aquatic fitness participants and aquatic therapy progressions. Sold as a pair of 2. Ergonomic grip channels maintain comfortable hand position through sets. High-density foam that won't waterlog, compress, or degrade with chlorine exposure. A standard piece of equipment for any aquatic fitness program.

How the Resistance Works

Water dumbbells work on buoyancy, not gravity — they weigh almost nothing in your hand, but the closed-cell foam fights to float, so the harder you push or hold them underwater, the harder the water pushes back. Each foam float displaces water and generates lift; the medium configuration uses two floats per dumbbell (one per end) to deliver a moderate, controllable resistance through the full range of motion.

Specifications

• Resistance level: Medium — up to approximately 5 lb of buoyant resistance per dumbbell when fully submerged in fresh water
• Float configuration: 2 high-density foam rounds per dumbbell (1 per end); 4 rounds total per pair, each 5.95" diameter × 2.5" thick
• Handle: 16" PVC bar with ergonomic grip channels
• Out-of-water weight: approximately 0.5 lb each (~1 lb per pair)
• Material: 4 lb/ft³ high-density closed-cell EVA foam (chlorine-resistant, non-waterlogging)
• Sold as: Pair of 2
• Use: Aquatic fitness, water aerobics, beginner-to-intermediate aquatic training, therapy

Resistance figures are calculated from the displaced-water buoyancy of the foam (Archimedes' principle) and represent the approximate maximum force to hold a dumbbell fully submerged; additional drag resistance is generated when moving the dumbbell through the water. Step up to the Heavy Resistance model (double the floats) for more advanced participants. Pair with swim belts and kickboards for a complete aquatic fitness equipment package.
