I love to work out at the gym, one day my friend decided she wanted to work out with me and asked me if I could work out for 2 hrs, I said sure no problem. When we got to the gym I said you only have water in your bottle try one of my sport drink packs tastes great and will help you work out harder. She took it added it to her water took a taste and said wow this tastes great. When we finally looked at the clock we had been working out for 2 hrs and still had lots to do.. our workout went 3 hours long and we were both energized,. she said I need to get some of those for my workouts, now she is hooked too.
