Hey, I've been reading these forums for awhile now, and I've seen alot of good advice. I have a question I hope you all can help me out on. I recently began a more powerlifting oriented routine in order to just gain strength. A friend of mine told me that if I run using interval routines (sprinting) that this will help out in the development of power as well. Any truth to this? He said something about making the anaerobic system more effiecient. Thanks in advance for any advice.
