The leg lifts, I might have called them something different, but I just lay on my back and lift my legs haha they're good for the lower stomach and sides.
Also, yeah man, I'm doing it at home, but I've gone down swimming and attached to the pool is a gym, I just need to get myself 2 days that I go and maintain those days for a few weeks, then build on it. Doing excersise at home is great, but I've had people say that it's much easier to lose motivation without regular days/ times organised. Swimming is good and if I can build that up to three days including about 20 or 30 minutes of gym before hand, I'd be delighted.
