5.0 out of 5 stars The best core training device, period.

The AB-Inforcer has not only revolutionized my training but it has also allowed me to be proactive in preventing injury. It truly is an amazing product. Athletically, using the device on a regular basis has given me more strength, power, and endurance across a broad range of activities. While mechanically, it has allowed me to strenghten my core as never before, helping to prevent injury and eliminate low back pain.
