I can give you some compound lift exercises if you want (snatch, clean and press, dumbbell swings) which do your whole body, while helping build power and strength. Maybe take this opportunity to bulk up your shoulders/upper back a bit?

I think I've put on a kg or two in the last couple of weeks as I've been sitting on my ass studying. Anyone else found studying makes you bloody hungry? I've been snacking on almonds trying to be healthy, but the quantity i have consumed can not be good for you
