The benefits of plyometric exercises Plyometrics are great for cardio, toning and fat loss here, we take a look at how the humble plyometric box can be a killer workout session.“The plyo box has been popular among athletes and hard-core fitness enthusiasts for a while now, but has become more mainstream since the introduction of CrossFit,” says elite trainer of over 15 years Matthew Strickland.“They are great for cardio-based and high-intensity training, but can also be used for rehabilitative purposes and for evening out physique imbalances.”Plyometric boxes and aerobic steps come in a range of heights and sizes to adhere to varying fitness levels and exercise goals. While fixed-height boxes are available and usually come in sets of three to four, try opting for a sturdy, adjustable step if you are tight on space. And if you aren’t confident in the jumps, we say go for foam rather than metal or wood versions: a lot less chance of skinned shins.For cardio/fat loss: Plyometric training involves using explosive bodyweight movements to exert maximum force in the shortest amount of time – making them the perfect fat-burning tool. Explosive movements also mean power and strength, especially in the lower body, can be achieved. Again, keep rest periods short and repetitions as high as possible – although given their taxing nature, sessions shouldn’t go much longer then 30 to 45 minutes.
