Ben's no-nonsense training vibe is to work hard and smart—no excuses. He cut his teeth working at one of the most well-respected gyms in the business—Mike Boyle Strength & Conditioning in Boston. Now, he has clients (celebs like Kate Upton, Chelsea Handler, and Jessica Biel) pushing heavy weights and running up and down the streets of LA (literally) pushing weighted sleds like it's NBD. His feed is full of casual workout vids of his clientele ("Bruno's Bitches") and himself crushing some classic strength work, as well as doing some new moves you probably haven't seen before, which is refreshing.

There's a reason trainer Kira Stokes' website reads, "20 years. 11 certifications. 0 bullsh*t." This woman means business when it comes to fitness. She holds personal training and performance-enhancement specialist certifications from the National Academy of Sports Medicine, as well as specialized certifications in Schwinn Cycle, pre- and postnatal fitness, TRX, SBT-Suspended Body Weight Training, ViPR, and Kettlebell Concepts. She trains her clients—including Candace Cameron Bure—using The Stoked Method, her namesake training style rooted in science. (Want a taste? Try the 30-day arms challenge or 30-day plank challenge that Stokes created just for us.)

Following Joe Holder (a Nike trainer and run coach and fitness nutrition specialist) will not only give you a peep into how Victoria's Secret models and fit-lebrities like Hannah Bronfman train, but will also give you a dose of exercise science education and a kickass reading list too. Holder is a perfect example of the phrase "never not learning." His expertise goes far beyond "trainer." The former college football player has coined his own holistic health theory, The Ocho System, and taps into both nutrition and exercise to train his clients for performance and functional movement—not just six-pack abs.

He has a master of science in exercise physiology and nutritional sciences from the University of Toronto and an honors degree in kinesiology from the University of Western Ontario.

Follow him on IG to see his healthy meals and his training with celeb clients, and to get a peek of his personal life—including the adorable ways he stays fit with his kids. (This Lady Gaga post may be the MVP.) Get a feel for his philosophy by reading about why he says exercise is the least important part of weight loss and what happened when one editor tried his Body Reset Diet.

Artemis Scantalides' motto is all you need to hear to become an instant fan: "I am not afraid to lift." Though her fitness life began with ballet and later Kung Fu (she's a black belt, FYI), she moved on to become a certified personal trainer, pre- and postpartum trainer, StrongFirst Team Leader, Certified Kettlebell-Functional Movement Specialist (CK-FMS), spin instructor, sandbag instructor, and Precision Nutrition Level I coach. Her posts will inspire you to pick up the heavy kettlebells and to find a sweat squad who will do it with you.
