im a boxer so cardio is vital to my workout. recently i have stopped cardio to increase muscle. i lose alot of muscle while doing cardio so i thought id ask for help here. how can i maintain/increase my muscle and size while still doing cardio. i find it really hard, it's a huge struggle because i need stamina and speed but at the same time my power and strength is equally important if not more to me.
i just started my first cycle ever also. i'm on sus250 for 2 months to give myself a boost in strength and size. any advice would be greatly appreciated.
