Does having too low BF levels hamper muscle growth? The best I have done is to add 3 pounds LBM but with 5 pounds of fat. This last HST cycle I tried to get another 3 pounds but without too much fat and ended up with nothing This next cycle is going to be cutting because I have more than doubled my skinfolds and lost my abs and I would rather be cut and small than big and fat! I started HST at 145 pounds, 29 inch waist and a 5mm mid ab skin fold and I am now 160 with a 32 inch waist and 11mm skinfold. I have been eating 1gm per pd/LBM protein with Zone ratio carbs and adding in extra fat to bring up the calories.
