Im soo getting confused ? if you do 30 to 45 min yes you will lose fat but you will also lose muscle because the cardio will go for your muscles as well for that long thats why i herd 10min of sprinting and slowing down will only have enough time to go for the fat to burn it off ? its like them skinny people that do 50km runs there skinny and no muscle because they do long long running and well its the same thing as doing 40 to 45 min in that time it will go for your muscles ?


i still want to keep muscle ? just lose fat ?

what im about to say will sound really really rude and im sorry but if you dont know 100% of what your talking about then dont give me advice for all you guys that have giving me advice can you please just be honest with me and tell me that after 45min of cardio can you still say that you have not lost any muscle? thanks
