A suspension trainer like TRX is a great way to make your home workouts more flexible and challenging: just hook the set of straps to a door or other sturdy anchor, and you're ready to go. This clickable graphic gives you a ton of ideas for what to do once you're set up.
The graphic comes from Stack 52, which sells a set of cards you can use to deal yourself a workout. But the graphic, and its counterpart for regular, non-suspended exercises, are free to use.
The graphic is set up so you can easily find the exercise you want: there are columns for different body parts you can target, and rows for difficulty level: easy, medium, hard, and insane. Hit the link below for the full version of the graphic, and then you can click each exercise to see a video of how to perform it.
