Good morning, everyone!

First and foremost, THANK YOU to David for posting in my absence. All day Monday, I was in Sunday mode due to the President's Day holiday and I totally missed posting. David is always willing to pick up the slack, and I greatly appreciate it, given the new obligations I have taken on since starting this board. THANK YOU, DAVID!

Here is your workout for today.

W7, D2
Brisk, 5-minute warm up walk
* Jog for 25 minutes without stopping

ENJOY YOUR DAY!

F22 triad W4D2 complete.
36 push-ups (with push-up bars),
50 sit-ups,
56 squats.

10K app W7D2... incomplete.

Bonked (dizzy and winded) with 6 minutes to go in jog. (FWIW, also been noticing light-headedness when standing-up from a squat lately.) Walked remaining 6 minutes of jog before normal cool-down.

Think I'll try a little carb-loading before next workout. Real sugar in coffee, maybe Gateraid instead of water during run. If that works, I consider this a one-off bonk and forget about it. Otherwise. I'll repeat week 7.

Been doing some web surfing on getting dizzy after exercise (thanks 20yearsyounger for pointing me in the right direction). Low blood sugar from dieting could be part of the issue but I think its more likely that my habit of straddling the treadmill to sip water during an extended jog is the main factor.

Called the "second heart theory". When people are involved in high intensity exercise over at least several minutes, they require a LOT of blood flow to the working muscles. So the blood vessels in our muscles, especially the legs, dilate to accommodate all this increased blood. Now, our body depends on contraction of our leg muscles to push blood from the legs back up to the heart. During intense exercise our ability to maintain adequate blood pressure depends on this pumping of blood back to our heart by our legs. If you suddenly stop running (exactly like when I straddle the treadmill), the blood return from your legs to your heart suddenly drops and so you don't have enough blood to pump to your brain (just like standing up suddenly). Our leg muscles act as sort of a second heart pumping blood back up to the real heart.

Since I was borderline hypertensive at the beginning of this year, I will take this as a sign that I am on the right path to a healthier body. All I need do is slow to a walk to take that sip of water. Will give it a go for this morning's workout.
