How can I get my arms bigger and defined I love Dana Bailey's arms do I have to lose more fat or should I lift heavy and less reps or light and more reps
Sorry I disagree with the whole depends on body type shit.
If your goal is muscular hypertrophy, you train til fail on multiple exercises. That's when your muscle grows, on those last 2 reps. A lot of people say go heavy. And to an extent it is true. Because if you go heavy you will acheieve failure quickly. But I totally disagree with that statement in its entirety. Because if you have been training 1 year or less, you shouldn't go and pick the biggest weight you can hurl to your chest in hopes to get "big". No! Your going to injure yourself if you don't have proper form. And btw proper form should not be taken lightly, your gains will reflect form. Above all else be consistent and research nutrition. You'll have to learn how to eat the way you want to look.
