So I use to be an avid weight lifter and then I took up running and lost all my mass. I am trying to find a happy balance between both with gaining mass as well as continuing my training for Marathons. Any suggestions?
Increase your protein intake. I've been trying to lean out and in the process I lost 60lbs of weight but am at a bit of a plateau. Still losing weight but I am starting to burn up muscle. I found this out when I went to see my university's health services department to work up a diet and get set with a traininer. (Private University has its perks.) You might want to see if your doctor can do this. They can track your progress and see what your body composition is and how it changes with the changes in your diet and workout habbits. They told me to increase my lean meats and green vegies. Hope this helps a little bit. I don't know anything about supplements so I wouldn't know what to advise you on when it comes to that but I've been doing this all natural. Good luck.
I'd alternate days as well. Having said that, training for marathons is a big commitment and also takes a lot out of your body. If you're running a lot of distances, it's going to be very difficult to make significant gains in mass. Good luck!
I have the same questions. I obviously need to pack on some muscles but I also want to be fit. Doing cardio just makes it a lot harder to achieve the normal weight I have been desiring for more than a decade now.
I am a marathon runner who also does weight training. I cross train to maintain my mass and build my endurance. I weight train 3 times a week. Run my long run once a week and teach aerobics 3 times a week. As I developed bulk I found myself getting slower but I recovered faster. My weight training days work the entire body especially legs. My leg workout are not for definition but endurance. I do not overload legs but instead work on reps of 12-16 per set. So far I have completed 49 marathons and am in reasonable shape.
