Delvis - you can see decent enough progress - and well done for being brave enough to post pics.
You do just need to eat/train more - but I understand your gym predicament.
Keep at it though.
Icebus - again well done for being brave enough to post it'll help as motivation, I promise.
Lots of people here have plenty of expertise and advise and will help you. The same addage of eat lots train hard and sleep well works for you too!
Mrk - Looks like you're in a decent shape - injuries don't help, I think bedding yourself in slowly is a good way to go, and then start hitting the big compounds with a lot of intensity and volume will help get you up to your target.
Sigma - well done to you for being brave enough to post a pic too. It's not easy having people look at you and judge you - but you've taken your first step to improving yourself and we can now offer advice and see what may or may not be applicable.
It is hard getting the motivation sometimes, I know I went through a phase where I didn't touch a gym fro 3-4 months. Just didn't want to do it. I was stressed, depressed, and bored of it. I then realised that I just needed a new target - so I set about getting lean and staying strong.
It's SO important to have a goal, but also accept that it's going to take TIME to get to that goal. Be patient. Train hard but train smart.
It's not just about doing big heavy weights all the time. It's about intensity as well, and recovery. Most importantly eating well. It's very easy to over/under estimate what you eat - if you really want to get "into" this, you have to start logging and understanding what you're eating and how your body is coping.
I've spent years working out how my body responds, and I've tried lots of supps, and fiddled about with different types of diets and foods. I now pretty much have that balance sorted and I think I know how my body reacts/responds to what I give it.
The key is not to change too much at once - and to just concentrate on things for a few months at a time.
IT can get obsessive and whilst I'm not bothered about doing stage/aesthetics, I am interested in the diet/training side of things.
It's hard work. IT's frustrating, and it can get depressing. Just walk away and have a break when it gets to that stage - it's easier than killing yourelf over it.
Most of all, ENJOY yourselves! And, ask for advice, but don't take shortcuts.
