Gummy bears, and homemade electrolyte drink. This is likely not needed when it’s cold, but is essential for me during the summer when it is warm. If it’s a hard workout early in the morning, I’ll add maltodextrin to the drink for extra energy. I try to keep on trainer nutrition very low cost. I do have some gels by the trainer that I use maybe once every month or so if I think it will help get through a hard workout, but that’s the only time I’ll use them.
