Energy gel is about 100 calories and it a combination of carbs that gives you energy to do sustained workouts. There are several brands (powergel, GU, cliff gel) but I an partial to GU in the chocolate flavor. You eat is about 15 minutes prior to your workout and then every so often (for a long workout) thereafter. It tastes like chocolate frosting and has almost the same consistency. It is truly meant for workouts more than 60 minutes and mostly for long events like marathons, century bike rides, etc., but I use a half packet in the morning before my workouts b/c I have to get up and get moving right away. I have no time to digest any "real food" but I need something in my belly or I will feel terrible, lightheaded, etc. and won't get through my workout. The energy gel gives me something to carry me through the workout but not too much (or I will get sick to my stomach). I also will use a half or full packet if I am feeling particularly tired or do a very difficult workout (boot camp) and I will notice that rather than feeling like I am ready to drop and losing focus at the end, I am much more "with it" and able to complete the workout with almost as much energy as the beginning. Don't get me wrong...I am tired! But I am not clumsy, exhausted, etc when I use the GU. It is something worth trying, if nothing else!!!
Stick with it and you will do better with Cathe's workouts. She is a tough cookie but when you nail them every time, oh boy will you feel the satisfaction! Christine
