I have heard good things about FIRST training plans on improving PBs and am quite tempted to use one of their plans.
One thing though - what is meant by cross training in the plan?
For me this could mean anything from weights to Martial Arts to cycling to hill walking.
I was planning on using this as gym time.
Any thoughts would be, as always, appreciated.
