Good luck to you.
I think it is important for fitness professionals to have great library to refer to when they have questions related to exercise science and physiology.
With that said I would suggest ACSM Guideline to Exercise Testing and Prescription in addition to NSCA Essentials to Strength and Conditioning.
In an ideal situation, I would also suggest taking out membership with both organizations so that you you receive their research journals on a monthly basis.
Best!
