Power development doesn't neccessitate the use of oly lifts, or moving away from heavy lifting. Complex training can incorporate the big three compounded with plyometric movements.
In essence the differences in a routine catered to each are thus:
A peak strength oriented routine (where moving the most to generate force mass is prioritized), will result in moving greater masses.
A power based routine will net results in moving mass faster.
How you get to each result varies from person to person.
- Complex training, as outlined above
- Higher repetitions (dan john says only do back squats in sets of 10 or more)
- Low reps (being strong is important no matter which route you are going)
- sprints
- Plyometrics
- dynamic lifting
It's all important and it all gets incorporated to varying degrees for both goals. What determines how you set up your routine? to answer that you need only discover what yeilds results for YOU specific to your goals and what benchmarks you can use to assess and quantify your continued development.
It's vague, but it's also the most complete answer you can get. Nobody should outline a universal strength or power routine. It's all specific to the response netted by each trainee to different stimuli.
