I'm currently trying to do the Stronglifts 5x5 weight training program and the Couch to 5k running program at the same time. I'm finding it hard to find time for both, especially with adequate rest. My experience tells that if I work out hard every day, or close to it, my immune system suffers and I get sick within 2 weeks.
Both the Stronglifts and the Couch to 5k programs prescribe 3 workouts per week. I'd like to change that to 3 days of Stronglifts, 2 days of Couch to 5k, and 2 days of doing nothing. I know theoretically that I could run and lift weights on the same day, but I haven't found that to be practical.
My question is: Can I do Couch to 5k (or any running program really) 2 days per week and still get good results? What is the minimum running frequency to achieve the desired results? Obviously progress would be slower, but would I still get there?
