Summer One-Up Week 6: Burpee Buy-In and 15-Minute AMRAP

Looking for a challenge this summer? Get ready to throw down with our fitness expert, PJ Stahl of PJ Stahl Fitness, creator of the TABATA Transformation System. Each week, PJ lays out a quick workout that measures your level of speed, power, endurance, strength, and skill. Think you can “one-up” our guy?

This week's challenge—a 15-minute AMRAP. You'll set your clock for 15 minutes and do as many rounds as possible of:

• -5 mountain climbers, each leg
• -10 wall ball squat cleans
• -15 situps

Here's the kicker: you have to do what's called a burpee buy-in. That's 20 burpees before you even start the workout.

A good score for this challenge is 10 rounds. But if you want to "one-up" PJ, you'll have to do more than 12 rounds. Watch the video for some helpful hints with the four exercises.
