Can't help on the before/after, sorry. But be assured that it shows, and I'm not an 'easy gainer.' Perhaps it makes more sense if I mention that this is the first real exercise I've had in well over a decade, so it amounts to 'beginner's gains.' (Or a damn long 'strategic deconditioning,' in HST terms.
It amounts to a surplus of about 875 calories per day, on average. Perhaps it will also help to know that my activity level aside from my workouts is quite low... i.e., I get a /lot/ of rest.
Thanks for these thoughts.
