One of the guys in the PT course was telling me about suspension training with a thing called a TRX. I'd never heard of it before, so I looked it up and it certainly looks interesting! Mind you at the price of a kit (£150+) it ought to be exciting.
A search for an alternative threw up some possibilities. So far the Rip 60 looks good value, but I just found a UK alternative called Flexstrap which looks rather inviting.
Short of poping to Halfords for some luggage straps and the Ellis Brigham for a Caribiner or two, these look good value at £60. I shall have to put them on my wish list!
