Greetings Gentleman...I could definitely use some advice regarding a workout regiment as I'm pretty clueless and there is conflicting info out there. I'm 47, in relatively decent shape...6'1, around 185-188. Midsection is decent although I want to tighten it up, but my biggest fault is my arms...they definitely could use some bulking up. I'm not out to get a 'Rambo' type physique, that's too much maintenance and would rather spend my time concentrating my energies on other things. I have a 20lb dumbbell included in my arsenal and I've started doing some curls with it...with both arms. I know: Pathetic. I also have been having some problems with mid-day mental fatigue. So can you guys help me out with a simple program to get started? Specifically, do I join a gym or just buy some equipment? Also how many 'reps' and stuff like that....Finally, any good advice on something to take to get over that mid-day fatigue? I work in commercial heating and cooling, which does involve physical activity to an extent, but nothing back-breaking. I need more RPM's to do more work, to make more dough also so any help would be greatly appreciated. Oh, I forgot to add this; Was married to BPD, divorced now,I have no kids and didn't take any financial hits. I laid on the mat and bled for a good 6 months and finally decided enough is enough...I'm not getting any younger and I want to resume my old life ASAP. I used to travel extensively, go to ballgames, concerts, etc. The common denominator was that I had tons of energy to do this stuff and this is my main reason for asking for help here. I want my fukn life back, yet I do need to get a tune-up to get rolling again. Thanks for your time guys and feel free to ask anything that I may not have included.
