I see what you mean. I think the difference between CT and ABBH/Westside is the number of times a bodypart is trained per week and the training split. Based on the numerous amount of routines that CT has posted, I’ve noticed that when CT designs a bodybuilding-oriented routine, he will have separate days for legs, chest, arms, etc. Thus, a bodypart is trained only once per week, which means that an entire week can be devoted to strength work for all the body parts.
ABBH focuses only on the compound lifts and calls for training upper and lower body 2x per week. Chad doesn’t believe in training arms separately (although he begrudgingly gave recommendations on how to add arm training to ABBH). Westside, obviously, also focuses on the compound lifts, and adds arm work and other assistance work based on a lifter’s weakness. Then again, with the Westside philosophy of switching exercises frequently, there are times when the assistance lift becomes the “main” lift. For instance, in Westside’s beginner workout, during the first 2 weeks, max effort squat day consists solely of finding a max in the good morning. Later into the program, GMs are dropped in favor of max effort box squats.
Now, CT’s powerlifting program, Canadian Autoregulating Training, is in line with ABBH/Westside, and actually works all 3 strength characteristics in one week. The “brute” strength day calls for working up to a 3-rep max, speed day is like Westside (I forgot the actual parameters), and there is a hypertrophy day that calls for working up to a 6-rep max. Each workout works all 3 powerlifts and mixes up the characteristics, e.g., a heavy squat day is paired with a light DL day. CT definitely used his head when he designed this one.
Okay, I have no idea what I just wrote, but I guess the bottom line is that if you want more of a bodybuilding-oriened routine that includes a day devoted to arm training, you’ll need to cut back on the other body parts to avoid overtraining. In that instance, it’s probably best to concentrate on one characteristic per week. However, if your goal is strength, stick to the Big 3 compound lifts of bench, squat, and DL, and you can work strength, speed, and hypertrophy, all in one week.
