A functional workout typically consists of compound exercises: movements that engage multiple muscle groups simultaneously, like squats, lunges, and push-ups. Instead of working one muscle in isolation, like many machines do, they challenge multiple muscle groups at the same time. For example, a squat works your glutes, quads, adductors and core. A push-up activates your chest, shoulders, back and core. Functional exercises are done using your body weight or with free weights such as dumbbells, kettlebells, and battle ropes, instead of machines. Compound exercises are important as they mimic our natural movement patterns. We very rarely use one muscle in isolation. Most movements we make work multiple muscles together, whether it’s bending down to tie your shoelace or reaching up to grab something from a high shelf. When you train multiple muscle groups at the same time, you’re working to help your body move better as a whole. Additionally, you’re preventing straining one singular muscle and causing injury.
