For a long time I was intrigued by the TRX, but put off by the price. I thought long and hard about making one, to the point of putting together a parts lists and seeing what I could use out of the REI.
In the end I did buy one and am so glad I did. I can't overstate how great I think this is. You can literally do hundreds of exercises on it, and get a complete strength workout.
Who should get one of these?
1 People who want to use it instead of a gym. You can save money this way. However I must warn that many exercises are very demanding, requiring not just strength but also balance and coordination. So beginners should stick to the gym.
2 People who are bored with traditional workouts. This is me. But with TRX you are always coming up with new exercises and variations. Plus, many exercises have quite a learning curve, reinforcing body skills needed in many sports.
3 Those who want an incredibe core workout. Best core workout tool ever.
4 Outdoor lovers. This thing is better outdoors, wrapped around a tree branch or trunk, than in the gym. Every workout can be in a different place
5 Travelers/campers/climbers. The whole kit weighs less than two pounds, and set up is easy, and for a long trip you can workout while you camp out.
6 Serious athletes of many sports. The total body demands of many exercises can only be completed with proper balance and form, which reinforces many sports-specific skills. Plus, the unit is so versatile you can use it to mimic or emphasize almost any movement pattern you can imagine.
it just looks like a bunch of straps. But when you put your body in the mix, the possibilities are endless. Extremely underrated!
