Well I'm impressed your knowledge of all that stuff.
I ended up going to the gym in the evening yesterday with my whole fam. I didn't feel like doing much so I shot for a goal of under 15 min for 2 miles. I did that and then just a few arm weights. I did core at home.
My nutrition is the same as I was doing before, following the paleo diet for athletes by Cordain and Joe Friel. Cordain wrote the book for non athletes first. I agreed with some things and didn't with other things...but when the one for athletes came out I felt it had more credibility to it being that Friel is a USA Triathlon and cycling elite coach. Hes tried this approach with thousands of athletes with amazing success in their abilities.
Its not anything really new. Its basically allowing 2 hour window before exercise and eating 400-600 calories for breakfast (I do closer to 400), breakfast is low fiber and low GI carbs with lean protein such as egg whites, protein powder etc. Shakes are OK and I rely on them often. The lower GI food paired with protein my stomach has time to digest it slowly (the protein slows the release of insulin) to replenish glycogen stores from the overnights fast. During a workout I make a drink thats 4:1 ratio of carbs to protein. Accelerade has been my drink of choice because I don't have to add any protein to it, it has it in it, and the taste isn't bad. I also hydrate 4oz of water every 10 min I'm working out. In a spin class, this is key, I sweat so much. Replacing glycogen as it is used up reduces fatigue and spares muscle in a hard workout. Keepying hydrated does the same thing.
30 min post workout I have a premixed "smoothie" (its melted) that has 12 oz oj, 2-2.5T protein and sometimes I add glucose or fruit if its been a heavy day. I do the smoothie within 30 min because its the most optimal time the body will recieve and store carbs. Doing it right away keeps the glycogen stores stocked and the body able to recover quickly for the next workout. Beyond that my first meal is lean protein with small amt of fibrous veggie and a serving or 2 of complex carbs. I normally do brown rice but last week I did sweet potato and it was SOOO good. As the day goes on I taper the starchy carbs and increase veggies.
anyway, its been working great. I have no idea where my cals are, but it seems when I don't focus on them so much and keep my nutrition well rounded and just do what I know I should it all works out better, less of a headache too
