Our expert reveals the most efficient way to get lean.


Q: What should I do if I only have 15 or 20 minutes to fit in a cardio workout?

A: Interval training has really gotten a lot of buzz lately, and rightfully so. It is by far the most efficient way to perform cardio, and in my "real world" experience, it has definitely proved more effective than steady-state cardio for sculpting lean bodies.

So, what exactly is interval training? In a nutshell, it's alternating periods of high-intensity work with periods of low-intensity recovery. For example, after a 3-5 minute warmup of moderate paced walking, you may sprint for 60 seconds and then walk for two minutes. Repeat this cycle six to eight times, and you've completed a pretty demanding interval workout.

The key to interval training is to continually increase the intensity of the work intervals over the course of several weeks. In other words, you should use the same intensity for three (maybe four) workouts before pushing yourself harder (faster). This process will ensure that you continue to progress at a safe and sustainable pace.
