Exercise can be just as polarizing as diet, with one camp claiming steady-state cardio is best for weight loss, while others swear by intense intervals of, say, weight lifting. Thankfully our girl Jillian Michaels is here to clear things up for Crossfitters and power walkers alike.

“The best kind of workout is whatever you show up for, really!” Michaels said. “Whatever gets you out of bed in the morning is ultimately going to be the most effective for whatever your goals are.”

Michaels herself aims to work out four times each week, and loves fitness that allows for measurable progress. While she admits to being extremely inflexible, Michaels says she is really into yoga right now as it feels rewarding to master each new position and see her progress visually.

As long as she can fit in at least 20-30 minutes of hard work in those four days each week, whether it’s a quick HIIT session in the middle of the afternoon or an early morning date with the gym, she can feel good about her fitness. And we know she’s not sitting at home watching TV the rest of the day—Michaels stays active as a mom, entrepreneur, speaker and activist, so she’s getting all those steps (or more) in. And simply staying active throughout the day burns more calories than you’d think!

Our favorite trainer does have some advice, however. If you’re looking for fast results to lose weight or build muscle tone, Michaels advises regularly switching up your workout in terms of reps, weight, intensity and even the type of exercise you’re doing to reap the full benefits. For example, if you’re a runner, try cross-training twice a week with a spin class or at-home circuit workout, and you’re likely to see some major running gains even though you’re doing it less.

Michaels is a big fan of high-intensity interval training, or HIIT, specifically for quick results. And she loves functional bodyweight moves like push-ups and squats that work several different muscle groups at a time. Plus, she says you should aim to get that heart rate up to 80-85% capacity and high-intensity intervals are sure to get you there!
