I also squezze legs in there somewhere (sometimes Tuesdays) or do them on a Saturday. Unfortunately I am your typical gym pidgeon although I do have a valid excuse. I snapped my hip off about 4 years back and I could not exercise my legs at all for 3+ years due to doctors orders. I was in traction for a few weeks and on crutches for about 4 months. No running, training or anything bar swimming and walking. Its amazing how your muscles dissappear if you don't use them. I had legs a supermodel would have been proud of. I am now slowly getting back into legs but I sometimes get an uncomfortable feeling when pressing 200+kgs as with my knees bent its putting pressure on the plate and pins etc
