Hello, I have almost 15 years and have trained 6 times per week as follows: Monday, shoulder and legs + HIIT Tuesday: biceps and back Wednesday: chest and triceps Thursday: shoulders and legs + HIIT Friday: biceps and back, abdominals Saturday: chest and triceps Training can either hinder my muscle growth?
I think following division Monday: Legs and shoulders + HIIT Wednesday: Biceps and back Friday: chest and triceps, abs.
