The good thing about exercise is that there are, literally, an infinite number of exercises you can do. The bad thing about exercise is that there are, literally, an infinite number of exercises you can do. Yes, there is "something for everyone"—great!—but just when you've got the meat and potatoes mastered, along comes the most innovative and fat-blasting workout you've never heard of, which leaves you thinking: Sure, I've do pull-ups...but am I doing enough goat yoga? (Hint: If you're doing no goat yoga, you're doing enough goat yoga.)

A healthy body is a confused body, with muscles taxed in different ways by a variety of unique movements. But since it's hard to know where to find new ones, we did the research for you, tracking down three personal trainers for their advice on which exercises could use a little more love (and, in return, will shower your muscles with love, albeit in the forms of pain and soreness).

"There are many variations of the squat, but doing a quality front squat has tremendous strength, core, and flexibility benefits unmatched by almost all lifts," says Booker. The front squat is like a—surprise!—squat, but with the weight on a barbell resting on the front of your shoulders, instead of on the upper part of your back. It's a bit of an awkward look, which is why Booker thinks most people avoid it. "People try it once, and if it feels wrong or doesn't look right, they quit."

If you don't quit, though, you'll see increased hip flexibility, leg strength, and core stability, all of which are important if you have a body and/or sometimes want to move it. "It's worth spending a year, if that's what it takes, to perfect it," says Booker. Just maybe mix in some cardio during that time, too.

Everyone wants abs, right? Right. But Okafor presents a pretty good case for why so many people avoid working them out. "It's painful. It's boring. And if you're not lean, you don't see the benefits," says the two-time Golden Gloves boxing champ. "So of course you're like, 'Fuck this.'"

Unfortunately, even if you can't see your abs, you need them: "Every time you get out of bed, you're doing a sit-up," he points out. Plus, a strong core protects your back every time you bend over or squat to pick something up, acting like a built-in support belt. In other words: Do the painful, boring work anyway.
