Leroy Colbert was the first bodybuilder to build 21 inch biceps 100% drug free. Below are the youtube videos where he goes into detail on how to build large muscular arms.


Leory would have 6 favorite bicep workouts and of those 6 he chooses 2 for his workouts. Leroy would train 3 times a week fullbody. Leroy would do 8 to 10 sets of 6 to 10 reps.

Biceps exercises he prefered were: Alternating dumbell curls (bring up to shoulder), concentration curls (scoop curls), seated barbell curls, reverse barbell curls, 21's barbell curls (21's is 7 reps half way up then 7 reps half way down then 7 reps all the way up and down).

Leroy recommends starting with 3 sets at first to develop mass. Once the muscle is big increase the sets shape the muscle.He would train first the muscle he wanted give the most emphasis for growth, which in his case was the biceps.


For triceps he would do the same 2 exercises for 8 to 10 sets of 8 to 10 reps. Sets were based on body's response.

Some exercises he prefered for triceps were: triceps curl, triceps bench dips,  and bent arm pull-overs.

Just watched a video by Lee

Just watched a video by Lee Roy ! His arms were as big in 2015 as they ever were. No way steroids. He would not have been able to maintain that arm size if it was.

He was natural. Do you see

He was natural. Do you see the fkn size of his wrists and hands, bro? Even today he obviously has big arms.I see guys on work release and some are jacked, using no roids whatsoever. It's called genetics. Most don't have the raw material to get those 21 inch arms, but some definitely do. Colbert was one of them. he's in his 60s, but I'm sure the man still has better arms than a lot of guys 1/3 his age- including yours.

Hes 82* Most steroid users

Hes 82* Most steroid users live to be 60.

I am not sure why all of you

I am not sure why all of you are always trying to hide the obvious fact. It doesn't take a brain surgeon to figure out that Leroy Colbert was not natural and his arms were never 21 inches. Why are you all refusing to see the obvious? 

Leroy was natural, steroid

Leroy was natural, steroid bodybuilder are more mass and have more veins popping out there arms.
