My current weight is 12 stone 7 pounds (@ 6 foot 3 inches) and am looking to get to at least 13 stone by the second week of september. My ideal weight is probably around 14.5/15 stone and cut - but that is wayyyyy down the line. Baby steps.
Am going to the gym three times a week, mainly doing big compound exercises such as squats, deadlifts, overhead press, bench, bent-over rows etc. Eating brick loads.
If i'm honest, you're an endomorph mate, never gonna be 15 stone without drugs.
You could add maybe 1 1/2 stone over a number of years......serious dedication required!
You'll fill out anyway over time, we all do!
How old are you? Just wondering. Would like to be able to bench my bodyweight, am around 20kg off that at the moment.
