The Waveweight is an 11-pound, hollow, ladder-shaped structure that can be filled with up to 24 pounds of water. As the water sloshes about in the twin tubes during side-to-side and overhead lifts, presses, squats, sit-ups and more, it provides “fluid dynamic resistance” that leads to better balance, agility, coordination and all-body functional strength-building than that available from static weights. The ever-changing unpredictability of water forces its user to constantly adapt, in theory generating enhanced muscle engagement. Several online videos teach strength and aerobic workouts.
