Just wanted to talk a bit more about plyos and keeping your HR up
As @chris_ottawa mentioned, plyos have very little use outside of making you better at plyos/explosive activities. In fact, plyos were first applied to help athletes conserve energy in explosive/power movements by training the ability of the tendons to work as springs.
On top of that, plyos are generally somewhat more high-risk than generic strength exercises. When you land, you ankles and knees need to absorb forces of 3-7x your body weight. I’m not at all saying that scare you, just making sure you’re aware of the costs and benefits associated with that style of exercise.
If your goal is to use an exercise to keep your heart-rate up between sets, I’d probably recommend a short (<60s) piece on a rowing ergometer or a stationary bike, or some type of loaded carry exercise.
Finally, there’s nothing that’s technically wrong with keeping your heart-rate up, but also consider that the heart’s ability to rapidly increase heart rate, then bring it right back down to resting rate is also important when it comes to long-term health.
