Moving from 5 to 10k - yes I'm looking at running further, how it feels right now I obviously need a greater cardio vas' capacity which should come by more runnung and continuously adding distance - but I'm pretty sure greater strength in my legs would help, calves, hamstrings, quads - in many respects - whatever the muscle, I don't really know or care!
I've been doing lungs and squats type stuff and have started using drum bells to add some weight. My question is - does this help, it is necessary and is it ok to do on the same day as a run? Once a week? Twice?
Is it sensible to do say a session of squats lunges etc say 20 minutes on the same day that I did a run? I'm trying to keep all leg work and runs on 3 days whilst doing some core and upper on another 2 with 2 as rest days. Sensible?
