Recently all of us at the shop started hitting the weights 3 times a week, and already noticed gains in just 1-2 weeks of workout.
I'm 36, about to be 37 and decided it's time to start working out (again) and get in shape, got a LONG way to go. I haven't worked out since I was 20-22 years old. Back then was benching 1x bodyweight @ 220 lbs. Now I am 6 ft 260 lbs and benching less than I was back then, but working my way back up fast. Gonna take some time to get to 1x bodyweight, that's my 1 year goal, but my short term is to get back to 200-220. Working out with the bar and 2 big plates, 10 reps x 4 sets right now, looking to step that up a little bit for next weeks workout, as the current is getting a little too easy for me already, gotta keep going up! Not looking to tone here, looking to build up the muscle, so I am going to be pretty aggressive with it by going up and up on the weight asap. If the workout doesn't make you sore, it's not gonna help you build up, just tone up. I'll tone when I get back to 1 x BW.... That's my philosophy about it anyway. Once I get my upper body in better shape going to start hitting the bicycle and work on my mid section and my legs. My legs are good shape, good genetics, but I do have 1 knee that I messed up so I can't do running, but I can do bicycle. Will probably get my weight back down to 240 or so, but I doubt any less than that if I am bulking up hitting the weights...
Anyway, to the OP, whatever you do, stick with it. As I tell my guys here that work/workout with me, ANYTHING is better than nothing at all. Commit to it and stick with it for as long as you can, in the long run it will certainly pay off well toward your "general state of health". Sharp pains are bad, dull pains are good. If you feel a sharp pain, you are doing incorrectly or have an injury that will force you to back down the weight/workout on that area. Luckily no bad car wrecks here, no sharp pains, just lots of burn from the workouts, it's not hurting that bad after a week or so though now... We started just recently again, already feeling way better, a little stronger, and looking forward to lots more workout. If I could hit the weights every day I would but I hear it won't work out good for you that way, every other day... Eventually on days not hitting weights will be hitting the bicycle, then back to the weights the next day, etc...
