Any tme I start working out now, my muscles grow by leaps and bounds instead of barely at all. I used to make a regular habit of chin-ups and push-ups, but there was not too much progress back then. I was obese, bloated and malnourished, etc. Now that I'm starting from relatively lean (18% body fat +/-) with proper nutrtion, it's easier progress. And I can take a week or two off and not lose much strength, if any at all.
