Hello,I a run track and participate in some fast races that have to be taken seriously. The 4x8 and the 4x4. I need to maintain my muscle mass while running these calorie burning races. I try to lift before and after my workouts but i am usually drained afterwards. And i try not to lift the day before a meet(i really feel it when im sore). Today i benched 185 5x5. Are there any specific things that i can do to help me stay strong and not loose weight?
