Good question - and one we all want to know the answer to. Accoring to our expert, Pilates HIIT exercises alternate between high-intensity movements that elevate the heart rate and controlled Pilates moves that engage and strengthen muscles, so as such, can be great for toning and sculpting. However, Warburton continues that there are some set backs. "It's important to note that Pilates HIIT is relatively new and hasn’t been as rigorously tested or proven as traditional Pilates," she shares. "The combination of dynamic cardio and focused strength training can burn calories and build lean muscle simultaneously, but the fast transitions between exercises, especially when pairing different balance and stability movements, may increase the risk of injury." This is important to keep in mind if you're keen to try the new trending workout, she stresses - especially because one of the primary aims of classical Pilates is to prevent injury. "Pilates was designed to promote control, good posture, and alignment. So, while HIIT Pilates can be effective, it may not offer the same level of body awareness and injury prevention as more traditional Pilates methods," she concludes.
