Many think that Pilates, like yoga, is just series of stretches, not requiring any particular equipment. Nothing further from the truth. Original Pilates equipment consist of a combination of springs and high tension elastic cords. This type of gear was so efficient that it became the model for many Pilates machines today.
Aero Piltes is one of them; many people swears that it's the best. It combines the qualities of Pilates workout (involving different muscle groups, while promoting balance and stabilising your body) with cardio!
Workout programs and techniques encourage a heavy workout of the cardio-vascular system that is more advanced and efficient then traditional cardio machines. At the same time you are not putting any stress on your joints/ligaments.
The machine even comes with four levels of elastic cords to promote varying workout levels. You can workout according to your fitness and strength abilities at four different levels instead of being limited to only one or two levels of training.
How does that sound? This piece of equipment should be available new from under £200. But if you are not a fitness-freak, you might be better off with good old Pilates ring...
