I'm 15 years old and I'm a baseball player. Im very strong in cardio, I run a 5:40 mile and I have almost no fat on me. I need to gain muscle to get better at the sport I love but my mom won't let me lift weights because she says its dangerous. My dad wants me to lift weights but I don't live with him. How do I gain muscle without lifting? By the way I'm 5'9" 140 pounds
