So I'm out of shape. I didn't use to be. I hit the gym since 16 and bulked and and got "beginner gains" very quickly and became a competitive rower (kayaker) in high school (well my country doesn't have high school but roughly that age range). I later was in reconnaisance in one of the fittest outfield units in my country's military service. I was in good shape. Not fitness model 8-pack ripped, but enough to have a sixpack showing and some nice cutting. I think I had something like 9-10%bf or so. This was till about 22.
But after I left military and entered one of my country's top business schools where it's competitive as hell, and I have to dedicate a lot of my time to projects, papers, and studying my guts out... which literally led to my gut showing up . I've gained something like 8 kg in a year and a half despite a reasonably good diet (as best as I can do on a hectic uni student's schedule) and gymming about twice a week (or about 7 times a month on average). I also play BJJ/grappling, at least once a week.
The frustrating thing is that I still maintain a decent diet - no fried stuff, mostly soupy stuff and occasionally western grilled chicken, steak, salmon, etc... My carb intake is about 50% of my meal, nothing excessive. I drink diet soda though. Admittedly it's nothing to compared to previously where I was chewing boiled chicken breast and salads (which are much more difficult considering I'm on campus now more than I am home), but still I eat decently.
Workout wise, I've tried a variety from 5x5, 4x8, and even back to the generic 3x10. I generally lift until failure, and I'm panting and more or less beaten. I'm actually stronger than ever, but I sure don't look it.
But I'd like to get back to looking and feeling fit. I just feel like a slightly chubby beefcake with a barrel chest and arms, but a big gut as well. That really sucks to see in the mirror when I used to have abs.
I'd like to know if there are any others out there who have or are in this kind of rut, where you used to be pretty fit and now you're stuck. Maybe you guys would have some advice for how I can get out of it, especially in terms of workouts or sports I can pursue. Most workouts I found online cater to beginners, who lets face it, get buff from doing 20 pushups a day. Or to advanced lifters on keto-whatchamacallit cycles and workout 5 times a week.
