So you can sweat smarter, not harder
By now you know that doing a HIIT workout earns you a big calorie burn that lingers post workout as your body revs its repair processes. But with infinite ways to approach a HIIT routine, the challenge is to find a surefire recipe for stretching out that bonus afterburn.
At the boutique studio chain Orangetheory Fitness, the winning formula that has created devotees in 40 states involves alternating between cranking up your cardio over a seven-minute block of time and doing a sculpting circuit. (For more interval training fun, try this tabata HIIT workout that also cycles between treadmill and strength moves.)
"You need to work out at a level that keeps your heart rate at 84 to 91 percent of your max for a cumulative 12 to 20 minutes," explains Orangetheory founder Ellen Latham, an exercise scientist who calibrated her classes to do exactly that. (Latham dubbed that heart rate sweet spot the orange zone, for the color coding on the digital screens in front of the class that indicate whether exercisers have hit it; class-goers are given a heart rate monitor that's synced to the screen.) Orangetheory classes are 60 minutes of musical chairs featuring treadmills and rowing machines for cardio blocks and free weights and TRX suspension training systems for strength blocks. The result: "The average woman will burn 500 to 800 calories during class and up to an additional 20 percent in the following 24 to 36 hours," Latham says.
Base pace: Moderate effort; 4 to 5.5 mph.
Push pace: Challenging but doable; 1 to 3 mph faster than base pace.
All out: Everything you've got; go about 2 mph faster than base pace.
0-2 minutes: run at push pace.
2-3 minutes: run at base pace.
3-5 minutes: run at push pace.
5-6 minutes: run at base pace.
6-7 minutes: go all out.
How it works: Warm up at your base pace (see Pace Chart, above) on the treadmill for five minutes. Then start with the treadmill block. Recover for 90 seconds. Next, do the strength moves in the floor block. Repeat the treadmill and floor blocks two more times, increasing your incline or pace and decreasing your reps each time as indicated. Do this routine for six weeks or more, two or three days a week. Try it with a set of 8- to 15-pound dumbbells and heart rate monitor.
