Yesterday I wrote about how pretty much all our workouts have, inherently, a relationship with interval training. I gave some examples of what that might look like, but today I want to talk a little more about how we might use the concept when we work out.
When we are doing our strength training, the exercises we do lie on a continuum from simple to compound. The more joints we are using, the more compound the exercise. The more compound the exercise, the more muscle groups we are using, the more calories we are burning, and the more body parts we need to coordinate to move successfully. In our analogy to interval training, then, our most compound exercises are our intense intervals and our simpler exercises are our periods of relative recovery.
In practice, this can take a variety of forms. One way to structure our intervals would be to superset an exercise with a more unstable version of the same exercise, such as regular squats followed by BOSU squats, or deadlifts followed by single-leg deadlifts. Another way to create this kind of interval is to superset a compound exercise with a simpler one, like following squats with bicep curls or Arnold presses with hamstring curls. (Note: when doing strength training, there is also actual rest that has to happen.)
In Pilates, our interval training would likely take on the character of doing related exercises that build toward a more complex version, followed by an easing off. So we might begin with chest lift and explore our way along until we are doing something like the long stretch series on the reformer or hamstring 3 on the chair or any of the tendon stretch versions, ending with something that brings us into extension like the rolldown reach on the spine corrector.
The common element here is that we understand and plan around the natural flow of our energy to get the most out of our workouts.
Go play.
