TRX PRO Suspension kit

What is it?

A portable suspension trainer, loved by US military types and personal trainers, that tightens the core more far effectively than the bog-standard elbow-to-knee crunch. It also improves functional strength, balance and flexibility. Suspension trainers have been knocking around the mainstream for a while in the United States ... and now they're coming to a gym near you (if they haven't already).

How does it work?

The TRX doesn't look like an exercise device par excellence: it's just two bee-coloured adjustable straps, a pulley system and stirrups/handles for the feet or hands. But appearances are deceptive. Wrap it round a sturdy branch, or through the gap of a closed door at home, and - provided you know what you are doing - the TRX will provide a punishing workout with a tweak of the straps and your body position, and letting gravity do the rest.

What's so good about it?

It's portable. It's different. And it works. After a month of regular TRXing, my stomach muscles were harder and my posture was significantly better. And it was fun too. There are multiple variations of basic exercises such as squats and push-ups, as well as ridiculously tough planks and suspension exercises to work through. You can focus on strength or flexibility, or put exercises together in a sequence with short breaks for more of a cardio workout.
