I wouldn't say I was lean, I'll add a photo tomorrow but I seem to carry my fat down my sides and towards the back. I get what your saying, I think I'm over complicating things for myself! I'm doing 3 days a week in the gym doing squats, bench, oh press, bent over rows, glute raises, bicep curls and calf raises, 3 working sets of everything plus warmups.
I'm not that strong, squat and bench have just gone over 100lbs for 6 reps but it's going up a little most sessions. I'm defiantly firming up and the weight's coming off so I look better. I think my biggest problem is I feel great losing the weight and scared of putting fat back on and it's become a mental block to me eating more, hence me looking for a way of gaining muscle without bulking up! Tracking how I'm doing is also difficult as weight doesn't mean much, should I just go by how I look, measurements or something else?
When you say about eating above maintenance, I've looked at loads of calculators and almost all of them give a different total. Would you suggest ball parking a number, going with that for a week or 2 see what happens then reevaluate?
