How to time your punches and kicks when using the AquaBlast Tether. Working with AquaBlast takes a little getting used to as you work against the forces of water against you and the bag. After striking AquaBlast, take a step back as the bag drifts away and the AquaBLAST bag reaches maximum extension. This allows you to pull the bag toward you for the next round of punching and kicking and allows you to control the drift of the AquaBLAST bag. You can quickly get into a rhythm as you workout in the pool.
