I dunno if you guys have seen this:
From Geek to Freak: How I Gained 34 lbs. of Muscle in 4 Weeks
This is very possible, also check out the Colorado experiment:
The Colorado Experiment, Casey Viator's Workout, Arthur Jones Nautilus Bulletin 1 2 3
exactly the same principle, these gains (the Tim Ferris ones anyway) were done with a Slow-Carb diet, and he at about 5000 calories a day over 6 meals.
These workouts are (High Intensity Workouts) and Tim Ferris did them 2x a week, each workout lasted about 30 minutes. Both the Diet and Workout are in his book(diet might not be in the blog, only the book), but consisted of eating lots of beans, meat, veggies and spinach. (He called it slow carb because of the beans...)
Anyway, Ive tried this myself, not with this diet but a full on bulking GOMAD diet, I was not able to eat 5000 calories a day, I gained about 7kg, 3kg was fat the rest muscle (7kg is about 15lbs i think) I went from weighing 67kg to weighing 74kg, this was in January, after where I took a rest from working out and started eating normally until start of April, In April and May I lost a lot of fat almost all that I had gained, and got my muscles back to the size I gained during the GOMAD diet in January.
Now I want to repeat my results in January but without gaining the 3KG fat, I will be doing the (High Intensity Workout) but I will be hitting more muscle groups than Ferris so I will need a longer rest period of about a week.
Ive looked into Vince Gironda and I might try the Cream Idea, Im only gonna be working out Once a week as I need the 7 day Rest period so I might lower the consumption of the creem throughout the week and load up before and after workout.
Like I mentioned before if youre interested in the High Intensity Workout visit Baye.com or read Body By Science.
