Original poster here, back again. For an intro, let me say I have had a stack of weights and a bench in the basement for a good part of the last 2+ decades (I'm 38).
Of course, my body does not look like I've been working out dilligently for 20 years, but I have tried to stay "in the game". I am 6'1", and last year this time I was running 218.
I am now down to about 186, mostly through maintaining a healthy calorie deficit and working out more steadily. I was doing cardio to get my weight down (rope jumping, stepper, bike), then bodyweight (pushups, pullups, dips, heavy bag), now adding more weight in again to build muscle on my new thinner frame.
At my age, I'm trying to be more intelligent, knowing that adding new muscle at 38 will not be easy (although I am a quick gainer when I get in a groove). I found this site during the summer, just posted now.
In the spirit of being more intelligent, I have been trying to understand the value of rest to growth, instead of a youthful rush at the weights 4x a week, so my question just had to do with soreness after starting a new movement, like a "pump" feeling 2 days later.
Should I let it subside before hitting the bodypart again, or hit it and work through the soreness. Is working it too soon going to be counterproductive, i.e. never letting the muscle properly heal & rebuild?
