Question: I'm currently trying to do the [Stronglifts 5x5](http://www.stronglifts.com) weight training program *and* the [Couch to 5k](http://www.coolrunning.com/engine/2/2_3/181.shtml) 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?

Answer: 
You're right, you should still get results, albeit slower.

However, you might consider lifting twice and running three times a week rather than the other way around. Given enough intensity (and proper rest), it is easy enough to see progress with lifting on just two sessions a week.

Or you might switch between blocks with focus on lifting (3xlift 2xrun) and focus on running (3xrun 2xlift). 2-4 weeks would be a good length for such a block.
I think you could do a running program consisting of 2 runs a weeks and still achieve "good results". 

One run should focus on a shorter and faster effort after a nice brisk warm up walk. And the other run should focus on a longer and slower effort after a nice brisk warm up. The shorter run should be closer to your 5K pace goal. The longer effort could be as much as 3:00/mile slower than your 5k goal.

Make sure you do a nice ~10 minute brisk walk before running and a nice cool down session afterwards. And, please don't increase your mileage/time/effort running by more than 10% each week.
