CrossFit Abs Workouts are a great way to build a strong, stable core that will protect you from injury and enhance your performances in the box.

This suggests that adequate rest should be considered for fatigue recovery when designing a back and hip endurance exercise program, and that future studies should investigate a rest time longer than 9 minutes for fatigue recovery following a modified Biering-Sørensen endurance test.
