The 1 Fitness Trend Jillian Michaels Says Is Beyond Dumb

To heat or not to heat? That is the question with new hot workouts continuing to pop up. We asked Jillian Michaels, author of the newly released The 6 Keys: Unlock Your Genetic Potential For Ageless Strength, Health, and Beauty what the one workout trend she wishes would go away is, and she didn't miss a beat in answering hot workouts, calling them "beyond dumb."

Of the misconception that cranking up the heat can help you to sweat and detox, Jillian told POPSUGAR at a brunch to celebrate AquaHydrate's partnership with the Breast Cancer Research Foundation. "You're not detoxing anything. Your liver, kidney, and spleen detox the body. And you know what helps them do that? Hydration." Jillian also emphasizes that you're not burning more calories "because your intensity is far less than it would be in a cooler room." So how much water should you be drinking? Registered dietitian Lori Zanini recommends drinking about half of your bodyweight (in pounds) in fluid ounces. So if you weigh 150 pounds, you would need approximately 75 fluid ounces of water per day, which breaks down into about nine cups per day (eight ounces in one cup). Drink up and stay cool!

Tighten Your Tush With These Booty Exercises From Jillian Michaels

Jillian Michaels is back with another hard-as-hell workout, this time targeting your booty. The former The Biggest Loser trainer, who shares workouts on her app My Fitness by Jillian Michaels, shared her butt circuit video on Instagram.

Since many of these moves require gym equipment such as dumbbells, weight plates, weight benches, and cable machines, it's best performed in a gym. Jillian recommends doing each exercise for 30 seconds and three rounds total.

With a mix of lunges, leg lifts, and one-legged deadlifts, these moves will target not just your glutes but your legs, too. Although some moves are more advanced, they can be modified to fit your level. If you're a true beginner, Jillian recommends starting with her beginner's program on her app. "So you can build solid foundation, get results, and not feel intimidated," she told POPSUGAR at an event for AquaHydrate. "You want to take action, but action that is misinformed is going to do a lot of damage."

Use this lower-body circuit as motivation to tone that tush, and get ready to put in work at the gym!

Jillian Michaels Shares the Biggest Mistake You May Be Making in the Gym

We all want to make the most of our workout time and prevent injury, so we asked Jillian Michaels, author of the upcoming The 6 Keys: Unlock Your Genetic Potential For Ageless Strength, Health, and Beauty, the biggest mistake people make in the gym. "Hideous form," she told POPSUGAR at an event for AquaHydrate. "One: that's totally ineffective. Two: you're probably going to get hurt." To develop proper form, Jillian suggests hiring a personal trainer for a session to take you through the exercise. If a one-on-one session isn't possible, looking to the internet can be an easy way to check the correct form prior to trying an exercise. POPSUGAR Fitness is a great resource when learning proper form, like these standing core exercises or fun moves with the pulley machine, like the cable pullover, for example.

Since beginners are most likely to make this mistake on form, Jillian recommends starting with her beginner's program "so you can build solid foundation, get results, and not feel intimidated. You want to take action, but action that is misinformed is going to do a lot of damage." Master your form before moving on to more complicated exercises and heavier weights. Your goal is to stay consistent and injury-free so you can keep working out.

Intimidated by the Sled? This Circuit From Jillian Michaels Proves You Should Take It On

Jillian Michaels may be a pro in the gym - the former Biggest Loser trainer is no stranger to challenge circuits and expert-level moves - but she also knows how to create workouts that are achievable for all fitness levels. Take this sled circuit she shared on her Instagram, for example.

While the sled may be an intimidating piece of equipment in the gym no matter how long you've been working out, Jillian proves you can get creative with it by adjusting your form and attaching handled straps to it. Although Jillian stacked her sled with weight plates, you could also perform these without weights if you're a beginner.

She started the circuit by running the sled forward. She then pulled the sled with straps while running sideways, followed by lunging sled pushes. She continued by getting into a squat form and pulled the sled with her arms in a row stance, followed by bear crawls while pulling the sled forward. She suggested doing each move for 30 seconds, and doing them back-to-back for three total rounds. If you need to take a break, take a two or three-minute rest in between each round.

Although Jillian made this circuit look easy, it's definitely a challenge! It's a total-body workout that will get your heart rate up and incorporates functional movements. Hopefully, this video gets you motivated to take on the sled and mix up your gym routine!
