If you can’t hang a heavy bag from the ceiling, the free-standing Original Wavemaster is exactly what you need for boxing, martial arts or MMA training. Whether you’re bare knuckled or using gloves, the Wavemaster punching bag provides optimal resistance and rapid rebound. Century’s Original Wavemaster offers 7 height adjustments, from 47” - 69” (in 3” increments). Its surface is covered with about 4” of high impact foam coated with durable vinyl, so you can hit it with significant force without worrying if it will rip or tear. To use, simply fill the base with water or sand to keep the Wavemaster steady. Its rounded base allows you to roll the unit for easy relocation. Available in black, blue or red.
