I've primarily been a long distance runner, but I have recently started incorporating swimming and upper body exercises into my weekly exercise program.
My latest addition is compound exercises like squat and dead lift. After a one hour proper introduction with a personal trainer, I was surprised to find I got really sore muscles the following day.
I realize these exercises affect my muscles differently than running does, but that got me to thinking: What's the long term effect of combining squats and dead lifts with long distance running? Is it mutually beneficial, a hindrance, or, perhaps, no significant mutual effect?
To clarify, I'm not taking up squat and dead lift to improve my running. I'm merely looking to see if there are any arguments for or against combining long distance running with squat and dead lift in my weekly exercise routine.
