Jamie – home stuff should be fine. I spent many years at the gym and gained three stone then left it at that – now do home stuff twice a week to maintain it and keep fit. I only have fairly simple kit but it works pretty well.
Same as you for cardio – have miles of countryside to run and cycle in – plus the sea to surf in!
With home stuff – just think of the time you save not going to a gym. Think of the lack of weirdos and posers. Think of how all the kit is available with no waiting and blast your favourite tunes out too!
