What About Pre And Post Workout Protein? Does It Matter?
Lesson 12 Module 2
This simple answer to this question, is yes. If you're interested in building muscle and maximising the effects of your workouts, then you need to give some degree of consideration to pre and post workout protein consumption. But you don't have to make it more complicated than it needs to be. Here's the abridged version of what you need to know.
- Consume protein 2-3 hours pre-training and within 3 hours post-training.
- If training fasted, consume protein within approximately 1 hour of training.
The protein you have pre and post training does not have to be whey, or a protein shake at all. However, a shake may offer a quick, convenient, and easily digested solution.
Here's the science behind those recommendations:
Protein feedings post exercise are needed to bring about positive protein balance, ie favouring Muscle Protein Synthesis, rather than Muscle Protein Breakdown.
Consuming c.0.3g/kg of high quality protein (eg whey) following training supports the muscle building process.

- This study compared a protein blend with whey isolate. Both resulted in increased muscle mass.
- This study shows the benefits of post-workout protein consumption. See table above.
