When I was 15/16 I really enjoyed contact sports (Rugby, Boxing mainly) and weight lifting (I'm male). Was quite muscular, in fact very muscular and strong for my age, probably since (genetically maybe) I have always been able to put muscle on easily. I honestly don't know and can't remember how big I was. For some reason, started to become more paranoid and self conscious onto how I looked and eventually I lost confidence rapidly. I began to shed muscle and in general lost weight, by simply running marathon style for ages and not doing any high intensity workouts for about 3 years. I'm now about 36 inch chest, 28 inch waist, and 10.9 stone (and 5 foot 11, but height increase might make the effects looks larger). I was much less bulkier (Much much less) and I feel better in how I look and definitely more confident. But family are telling me that I'm wasting, and that I don't eat right, which I do, just not as much as I used to in order to have the energy for the high intensity workouts that I did. I get comments from my friends and girlfriend all the time about it now. I know its a problem, but I don't seem to want to do anything about it. I'm not particularly bothered about it, since I enjoy my 45 minute runs 3/4 times a week, but I just don't want to upset my family and other loved ones, since they're worried for me. Is there anyway I can tone up without having to increase in size? I'm not bothered if there isn't, I think I just need a bit of my strength back without risking what my willpower has worked for.
Should I still go?
