Can maximum strength (practiced 2 per week with 48-72 hrs rest) be trained concurrently with hypertrophy?
Conjugate Training
This means training different type of Strength in the same Training Cycle.
Research shows when one type of Strength Training carries of to other types of Strength Training.
Dr Michael Zourdos' Research
Zourdos found that a weekly Training Program that included: Hypertrophy, Power and Limit Strength (1 Repetition Max) increased Limit Strength.
Zourdos' found that setting aside specific days for each type of Strength Training in a certain order produced optimal results. It went as follows...
1) Monday: Hypertropy
2) Wednesday: Power
3) Limit Strength
Westside Powerlifting Method
This method has been around since the 1980's and has proven to be effective. As Bro posted, West Side usually performs Hypertrophy after Strength Training.
Non-Linear Periodization Training
Zourdos and The West Side Powerlifting Method are Conjugate Training, more Non-Linear Periodization Training Protocols.
Or is it better to have a pure hypertrophy period, followed by maximum strength period?
Traditional Periodization Training
Devoting a Training Cycle to specifically one type of Strength Training is Linear Periodization Training.
The Traditional Periodization Training Cycle focus on one type of training at a time...
1) General Physical Preparation (Conditioning)
2) Hypertrophy
3) Power
4) Limit Strength
Non-Linear Vs Traditional Periodization Training
Both method work.
Length of Training Cycle
The length of a Training Cycle is largely dependent on your "Training Age", how long you have been training.
Novice Lifters can make progress on a long Training Cycle (8 - 12 weeks), performing the same routine. That due to the fact that Novice Lifters adapt much more slowly to a program enabling them to make progress for a longer period of time.
Advance Liftersadapt quickly to a Training Cycle (3 - 4 weeks). That means they need to vary their program more often to continue to make progress.
