Whey protein isolate is your - from the ground up - building block for good muscle health.
When you build a building, you first have to construct a foundation.
The foundation must be square, level, and plumb.
If the foundation is not square, level, and plumb, everything you build on top of it will continue to be the same.
You can make adjustments along the way to correct the problems as they appear, but this creates extra, unnecessary work that could have been prevented from the beginning with proper installation of the building blocks.
Whey protein isolate is the proper foundational building block.
Your workouts are meant to build a strong body.
A strong body is made up of muscle and bone.
Your muscle brakes down during the day whether you workout or not and it needs to be replenished with nutrition.
More is the case if you have a daily exercise and workout routine, and protein is the nutrition that builds and repairs.
With out the intake of protein after workout - which can be compared to building on top of a poor foundation - the body will begin to damage easier.
The food we eat on a daily basis does not provide enough nutritional replacement to rebuild the torn down muscle of a daily workout routine.
Therefore, without a replacement program like the daily intake of a whey protein isolate type product, days will have to pass after a workout to allow for muscle to rebuild before working out again.
At this rate, working out to build muscle will take much longer and will be much more painful due to muscle pain and body ache, preventing the desire to go back to the weights.
Whey protein isolate is a great product for building muscle and for preventing damage and pain.
