Pushing yourself to your max is a key component to re-creating your favorite studio workout experience.

Image Credit: RichLegg/E+/GettyImages By now, your favorite HIIT and circuit workout classes may seem like a distant memory — the high energy, the loud music and the high-fives. Unless your fitness studio is streaming their classes or they’ve moved everything outdoors, you might be longing to recapture the magic at home.

 Part of what makes these classes super effective is the effort you put it. The goal is to push yourself to your maximum effort, which is much easier to do with a coach cheering you on than alone in your basement.

 But if you have a heart rate monitor or fitness watch, you can use that number to get you in the zone — both mentally and physically. Ideally, you want to focus on getting your heart rate between 84 to 91 percent of your maximum heart rate for six to nine minutes of a 20-minute workout.

 You can calculate your maximum heart rate by subtracting your age from 220. For example, if you're 35 years old, you maximum heart rate would be 185 beats per minute. You can also use your rate of perceived exertion (RPE) to track your intensity. Your RPE should be at about a 9 on a scale of 0 to 10.
