Best YouTube workout Videos

This workout's scientifically-designed to get you maximum results in the shortest amount of time, which is probably what you're looking for if you're working out at home. Also, it uses cartoons for the demonstrations, not people, so if you find pretty much every fitness instructor you've ever had annoying, there's hope you might actually like this one. The only downside is that the music's a little annoying (okay, a lot), but that's what your late '90s Britney Spears Spotify playlist is for.

Tone It Up's Butt Workout

If you're one of those people who finds watching the Victoria's Secret fashion show while you work out motivating, you'll be into this. The girl looks like a cross between Shakira and a Southern sorority girl, and the beach setting makes it pretty hard to forget that while it's winter now, bikini season is coming. Oh, and the workout is good. You'll need kettlebell to do it, but kettlebells are awesome and take up as much space as a wine bottle, so you should own one if you don't.

Mary Helen Bowers' Ballet Beautiful

Mary Helen Bowers was still dancing ballet—on point—when she was nine months pregnant. It was nuts. That's just who she is, though: the fearless leader of the ladylikes, the type As, the perfectionists in search of "long and lean muscles" workouts. If you're one of those, you'll love this. It's challenging, and just, you know, beautiful.

David Kirsch's Arms Workout

I've worked out with this dude in person before, and I can tell you that he is TOUGH, so it makes sense that his workout videos are too. And while he has a bunch of videos that target specific areas, I really love the arms one for quelling that "do I have tharm?" anxiety. Plus, it's fast, because honestly I probably wasn't going to spend more than five minutes working out my arms anyway.

Jane Fonda's Advanced Workout

The clothes are awesome (WHAT are those high-waisted, brief-style workout underwear things?!). The Flock of Seagulls hair is awesome. And even if the actual film's a little blurry, that just makes it all the more legit. If nothing else makes you want to work out, there's something just really funny about doing this in your living room with your roommates. (Neon leotrards encouraged, not required.)
