I like to do at least 30 min of cardio after my workout...i have heard that you need to get your protein and carbs in at least 30 min after you workout...sucks cus i live like 15 min from the gym...so if i do cardio then drive home thats at least 45 min after my workout before i get anything in my body...so what is the longest time you can go after workout before getting any protein or carbs??
