Look at Interval Training / HIIT / Fartleks -- you shouldn't be doing hours of cardio in a gym for weight loss. And look at doing Resistance training before you do those.. (Basically -- Alwyn Cosgrove's hierarchy is probably the best guide: http://alwyncosgrove.com/2010/01/hierarchy-of-fat-loss/ http://alwyncosgrove.com/2010/01/hierarchy-of-fat-loss/ ) Long hours of cardio are what you do when you a) Really enjoy it and b) Have time. If it's a nice day - go for a bike ride or a run... but if you're stuck inside in the gym - optimise your time.
