Terry Laughlin will cover the elements of the "speed problem" in swimming, why the traditional means of swimming faster seldom work and why an often-ignored approach is virtually foolproof.
Should I be working on getting faster at running by doing the longer distances and working up slowly over time or run faster for shorter distances now?
I don't really strength train (because I never have and don't really know much about it) and feel like my lack of upper body strength is the reason why I'm not getting faster.
