Hi Art
This dizziness happened to me once with a trainer also and I had been training for years before so it isn't like I wasn't used to working out. What I chalked it up to was firstly, because the trainer made me do a whole series of different exercises that I wasn't use to doing, using different muscle groups and muscle fibers that had never been used before. Secondly, because I was with a trainer I was working much harder maybe to impress her? She was also making me work hard because she knew I could handle it. Also with a trainer I find they only have a specific amount of time to show you so they move you along quickly to be able to incorportate a lot exercises in the alloted amount of time they have with you. I was dizzy and shaky all over after this workout. It soon passed though and I wasn't sorer the next day than I usually am after a good workout.
Foodwise I eat fairly close to a workout. I usually eat oatmeal and eggwhites this combination, for me, is the best pre-workout meal. It keeps me satisfied without feeling overly stuffed. I eat and get ready to go to the gym and by the time I get there a good half to 3/4 hours has passed enough, for me, to be digested but not long enough to be completely gone from my system, I stay at the gym for 1.5 hours usually, then when I get home I have another post-workout meal... Sometimes, again I have oatmeal and eggwhites, I know I'm boring
, but it works
