You can guarantee this?
I'm 85kg now and my are 15 1/4 inches.
I've been up to 93kg before (8kg heavier) and my arms were a touch under 16 inches.
I am currently drinking about 2 1/2 litres of milk a day.
I do squat, not 20 reps sets 2-3 times/week.
Do you think the extra bit of milk and squat program will make the 7kg weight gain benefit the arms more than other bodyparts?
I know what you mean, but I don't think it would work in my case.
I see how squats will put on overall size, but how does is it contribute so heavilly to arm size?
