How do you keep these refrigerated after a 4 hour work out?
The biggest issue for me is taking advantage of that 30 minute window, because after I finish my last set it usually takes me 3-5 minutes to catch my breath, another 2 minutes to put weights away and clean off my station. Add 3-6 minutes to walk to the locker room, retrieve my bag, wash my hands and use the restroom.
In a best case scenario I've wasted a minimum of 8 minutes of the post work out window, thats almost one third of the window gone just putting stuff away. That's not considering I still haven't refilled my gallon but at the drinking fountain.
