I love the gym! but agree you need to keep things fresh and change your routines once in awhile so it dosnt get stale.
I like the treadmill been using for quite a few years now and i reallly mess around with it, ie use inclines, slow down, start fast or just push myself on that last stretch goal that i set myself.....but must have music! its what pumps me up...Justin Bieber really gets it on for me!

....Na some good rock/trance dance stuff the best.
Rower i use to hate, but it really works your arms as well as legs and since i set targets and am alot fitter and is more fun.
I do weights to, and with the cardio i can spend up to almost two hours excersing, but its fun to me and a great buzz after, luckily i have weird shifts so helps.
BUT and a big BUT i love cakes/chocs had a little blip this week and finished off a box of the little blighters!
but been to gym three/four times a week and roughly 1100 calories lost per session, so will be happy come sunday weigh in if i break even.............there may be beer later to!...hell you got live to
