After turning 40, I knew that it was going to be time to start getting serious about working out. Being a naturally thin person for most of my adult life, I was really able to keep my weight down, and a pretty decent amount of muscle tone, even though I wasn’t working out very regularly. I’ve never cared for getting sweaty, and 18would rather spend my time window-shopping or writing or crafting. But after hitting the 4 decade milestone, I noticed that my pants started getting a little tighter, that muffin-top got more pronounced, and generally I just didn’t feel as tight anymore.
