it was for me. Thanks for the email. There are some things with the study i think are off. For one the volume, they only tested a maximum of 5 sets per muscle group per workout in advanced trainees, either twice or 3 times per week. They did not test a condition that i advocate, high volume 1.5 times approx per week. I think that is greatly insufficient for a bodybuilder to grow. There are also other factors unaccounted for such as nutrition. I really dont think i would benefit from 4 sets per muscle group twice a week as much as I would 30 1.5 times per week, 4 is like a warm up. Granted strength is associated with hypertrophy, however you can still get stronger performing ways i advocate. I agree damage is not necessary, however it certainly is a factor in bodybuilding, 4 sets will not elict enough damage. |
