If you are looking for the most effective way to achieve your fitness goals, you need to try high-intensity interval training (HIIT). HIIT workouts are a proven way to improve endurance, burn more fat faster and minimize training time, while still increasing strength and power.[1]
HIIT workouts involve performing exercises at maximum intensity for short durations followed by limited rest intervals. Each rep should be intense, rating at least an eight out of 10 on a perceived scale of exertion. If you aren't out of breath and gassed after a complete circuit, you are not working hard enough.
Performing the following TRX Rip Trainer HIIT circuit will "hit" every muscle in your body while targeting critical aspects of performance, including strength, balance, power, endurance and mental focus. Although intensity is important during HIIT training, attempt to progress to faster and more powerful movements, and never sacrifice control for intensity.
This exercise will load your core by activating your abdominals, hips, low back and scapular muscles. Developing these muscles will improve your posture, balance and power transfer and reduce the risk of back injury. In addition, performing this exercise at a high speed offers a tremendous metabolic challenge that will improve your overall endurance and increase fat burn.

The Rip Kayak develops your posterior chain (muscles in the back of your body) in an offset foot position to challenge your balance. This will increase pulling power in a balanced position, while still challenging your heart and lungs.

This exercise is about speed, power and agility. It mimics an Olympic-style lift, but it adds a rotational component to challenge your core. It should be performed with max effort each rep while maintaining a wide, stable base and using perfect technique. Be prepared to be gassed after this exercise.

Once you've mastered these exercises, head to our TRX Exercise Library for more moves to round out your TRX workout.
