[General fiction] I've recently developed powers beyond humanity's limits and as a result, I now have a physique of a Greek deity. How do I hide my newly-muscular body from my associates without raising concern?

Due to an incident which I am by no means going to divulge here (as I don't wish to be identified and explaining my predicament in detail could help others figure out my identity) I have started to develop superhuman powers. By some stroke of luck, I have been on my legally-mandated vacation and so I was able to quickly leave town in order to go into seclusion and learn to understand and control my powers.

In short run-down, I can now fly at mach 5; punch through rock; lift a junk of stone twenty feet wide with only one hand; casually toss said rock thirty miles away with a flick of my finger; run 500mph; get struck by the twenty foot-wide rock with no injury; shoot lasers from my eyes which can melt rock in less than a second; and submerge myself in lava for several hours (and without damaging my hair follicles).

As of right now, I am uncertain whether to become a superhero, either as a volunteer or as a government-backed agent and would much rather enjoy my privacy for now... except I'm due back to work next Monday and I happen to have grown from a scrawny nerd to a highly muscular frame somewhere between the realm of "Mr Olympia" and "Strongman competitor".

My question is simple - what are some easy and affordable ways to hide the fact that I've gained, at the very least, two-hundred pounds of muscle?

Edit: Also, how do I do so without my powers possibly damaging my clothing?

"Yeah, the workout routine is a bitch, but it's really paying off right now. It's weird, but you're the first one to say something..."

Unless you've never worn anything less than a 3-piece suit around these people, someone's going to notice. Which means the answer is to gaslight those fuckers. 

Use the rest of your vacation to study up on physical fitness, cram school style. Be ready to shoot off information on nutrition metrics, recovery times, cheat days, who has the best price on creatine powder, and so on. When you go back to work, when someone says something, you look them dead in the eye and tell them you've been on a super-hardcore health regimen for about half a year now. When you're around someone every day, gradual changes go unnoticed, and it's a lot more plausible that you've been slowly beefing up than you going from the "before" pic to the "after" pic in a Charles Atlas ad in a week.
