exactly what i was thnking. you dont seem to be that strong for your sizeOnly been traing proper for 18 months, im still losing weight remember, i aint 16 stone of pure lean mass lolyou are weak for your size,training time ,you mention that you bench 100kgs quite alot but that's less than your bodyweight not really impressive.start squating and get your deadlift to over x2 bodyweight...
