Crunch and kick
The crunch and kick exercise is excellent for developing core strength and defined abs. The Rooboard increases the intensity and shortens your training time.
If you’re a busy professional and take your six pack training seriously the portability of the Rooboard means you can train anywhere, anytime.
The Rooboard creates instability and tension due to the core and stabilizer muscles being forced to engage. This means you can reduce your training time without losing the intensity.
