>Cross Training>Boot Camp/HiiT Training
Lots of folks. Usually sail right on by them about 200 meters into a 5K. Otherwise fine for general fitness under competent supervision.
Hmmm... So do I if they're not runners. But I've successfully combined it into cross training without losing running speed
Boot Camp (12 months and going):
I gained speed and set new PRs at age 47. I also had much greater endurance in my 50k runs.
I think its a balance. I am female and do not wish to be bulky but I love that my arms and back are so defined. I also see better muscle definition in my legs that running did not provide. The first mile no longer sucks and I can run hills with great agility.
I think that the boot camp style of working out touches on all muscles and is GREAT for trail runners. The example I give is that, while running a trail marathon, I tripped. By tripped I mean that I was flying through the air like superman I Ianded on my hands and toes, without my face or knees making contact, and I slid about 2 feet in a high plank form. That surprised me and aside from scapes on my hands I continued on without injury. If I ever wondered how strong my arms and core had become, I had the answer in that moment.
