I completed the LiveFit program earlier this year... finished in February.
I would recommend it if you are a beginner to weightlifting. I wouldn't recommend it if you don't want to dedicate EVERY DAY to going to the gym for twice as long as a workout should take. Sometimes I'd be in there for two hours to get everything done.
By the third phase you are trying to superset multiple MACHINES which is just douchey to do at a gym, and yes I have ran into people doing so. "I'm using this machine, this machine and this machine. Sorry." Give me a break.
My recommendation is to follow phase 1 and 2 in a way that you can accomplish it. Supersetting the SAME movements with each other is just dumb. Jamie does it a lot in Phase 2 and 3... I suggest mixing up the exercises and subbing something else for any exercise that doesn't make sense to do at the time. It'll happen often.
