This exercise will maximize your muscle-mind connection. As with all isolation exercises, use a long time under tension to create metabolic stress. Stay focused and let your abs do the work rather than racing through these.

• Hook your feet into the straps of a suspension trainer and assume a push-up position.
• Bring your knees in towards your stomach while lifting the hips and crunching your abs.
• Extend back out to a full push-up position and repeat.
