Wheatgrass and fruit is proving to be one of my favourite pre-gym snacks. It gives you the quick energy boost that you need before a workout. I am definitely loving the health benefits of wheatgrass and think it is helping me improve my energy levels and stay healthy. Fruit is always a great snack before the gym as the sugars give you a natural energy source and it helps you eat at least five portions of fruit and veg a day.
