air walker just swings back and forward with your arms and legs and other is more like being on a bike without sitting down if you get me they are more hard work

cross trainer then but swimming may be good

cheers for replying

Er whats the conection with sheffield ?

Gravity walkers are rubbish, they don't do anything. Cross trainers mimic running, personally I think a treadmill is better but they're still quite good.
