What was your first and how well did it work. Here's mine copied from my 1990 log book.
It was my slight variation on an Ellington Darden routine from the book Massive Muscles in 10 weeks.
One arm row
DB bench press
Cross Overs (with tube)
Lying tricep ext
Db tricep ext (seated, single db in both hands)
1 set of each for 6-8 reps, performed one after the other with no rest at all, took about 30 minutes to do. Did it Monday/Wednesday/Friday for 16 months without a "single" missed w/o, took me from 9 stone 10 lbs to 12 1/2 stone and my chest from 36 1/2" to 43", put 4" on my legs and 2" on my arms.
I must point out it also coincided with me moving out of my parents house into my own place and suddenly being able to control my own portion sizes!
So what was yours?
