A crossfit plyo box is more versatile than many give it credit for. Aside from jumps, it can also be used for other types of lower body, core, and upper body exercises. In fact, you could string these all together to create a circuit routine. Ten minutes is all you need to get your heart rate up.
For example, you might alternate between lower body and upper body or core exercises at 30 seconds each. Start with step ups and step downs. Follow this with pushups where your hands are on the box and your feet on the ground. Switch to lateral steps crossing the box then perform bridges with your feet on the box.
Try box jumps at the lowest box height then transition to a plank-around-the-world with hands on the box. Perform jumps again at a slightly higher elevation and move to push-ups with hands on the ground and feet on the box for greater difficulty.
These are just examples of what you can do. Talk to your trainer to customize a routine that’s right for you.
