Measure your heart rate before, during and after work outs and write it down. Monitors can be worn as a strap across the chest, on the wrist and even on the head, and by measuring your heart rate can help you exercise at the right intensity. Most don't have a display, so you'll need to connect your monitor with a sports watch or smartphone app to see your heart rate.
I'd say none of the above! If you're planning for yourself you'll want to choose foods you like. It's imperative that in planning meals for anyone you consider their allergies, you don't want to kill them! Your available finances are also important, if you can't afford to go to a fancy restaurant, don't!
