At a point in my life where I'm starting to notice it's not as hard to gain weight as it once was. Part of that I'm sure is just my activity level on a daily basis. When I was in high school, I tried like hell to gain weight. I struggled to get past 135. Eating like crazy every day and working out twice a day, four days a week with heavy lifting (with a lot of natural cardio mixed in from soccer and track), I was able to get up to 150 by the end of my senior year in high school. Freshman year of college, I continued my four-day-a-week workout program with weightlifting and mostly stopped doing all the cardio. Somehow, I lost 15 pounds and was back down to 135. Sophomore and junior year of college, I worked out sparingly but my weight stayed around 140. My senior year I got into working out more frequently and got back up to 150-155 or so. About a year later, I'm now up to 165-170. Most of it is good weight since I've been back into a more-or-less, four-days-a-week workout routine. But I'd be willing to bet my body fat percentage is slightly higher than it used to be. Anyway, long story short, I'm at the point where I'm wondering if I shouldn't actively start focusing on doing more cardio. Very curious to see what happens to my weight if I don't work at gaining or losing, but I want to stay in good shape. Anyone got any recommendations when you went through a similar period where it seemed like either A) your metabolism is slowing down, or B) you're just filling out a little more? How did you adjust? Thanks for any and all thoughts and advice in advance!
