Am away from home and my weights, so I begun working on pushups, doing ten counter pushups throughout the day yesterday. Also tried squats, with rather less success- if I try to do a deep squat I keep falling (into the final squat position, so no harm done, but I doubt it's good form) and I could only manage five or so. But my legs are sore in that 'hello, we worked out a lot yesterday!' so I guess it's doing something!
