Drop and give me82? That’s right. We at Greatist love—nay, adore—the push-up. It’s one of the simplest and most functional exercises around, and it works almost every muscle we’ve got: the triceps and chest get a great workout, but the movement also engages the shoulders, core, lats, lower back, legs, and glutes.

Doing the same old push-ups day in and day out can feel a little vanilla, so we’re here to shake things up. Variety can supercharge a workout and throw a whole range of new muscles into the mix. Ever tried a spiderman push-up (see No. 15 below!)? How about an alligator (No. 13) or a jackknife push-up (No. 34)? There might be no end to the different spins (and cool names) we can give this classic exercise, but we’ve done our best to bring you as many as we could find, arranged into five categories: beginner, intermediate, explosive, wxpert, and equipment-based. Just be sure to spend some time perfecting your form and nailing the basics before you jump into the variations that require increased strength, coordination, and balance.

Note: There is no International Push-Up Authority, Official Push-Up Certification Board, or anyone in charge of naming the different kinds of push-ups. Consequently what some might call a rotational push-up, others will call a T-push-up, and so on. We’ve strived for accuracy, but concede that some people might have different names for these movements than we do, and that’s why we linked a video for every one of the entries!

Beginner Push-Ups

There’s no shame in starting at the beginning! These exercises will help build the foundation of strength required for the more advanced variations—plus, anyone who’s done a good old fashioned standard push-up knows that it provides a dynamite full-body workout all by itself. Remember, don’t take on an exercise unless you can manage a full range of motion—if taking a push-up all the way to the floor is too difficult, scale back to a modified push-up on your knees or a wall push-up (both of which are explained below!). Good luck!

1. Off the Wall
This is the first step on the path to push-up dominance. It’s basically a standing push-up done against a wall, which greatly reduces the amount of weight the muscles have to support.

2. Off a Table
The trick to building up to a standard push-up is to start from the wall and gradually get more horizontal. Push off of a table or chair on your way down, and you’ll be there in no time.

3. On the Knees
Nearly there! This is identical to a regular push-up, but performed on the hands and knees, with the feet raising off the ground as the push-up goes to the floor. This takes a lot of the work away from the abs and legs, making it a great way to practice for the real thing.
