A Quick Health Question

Three days a week I work out. It’s about 50-50 aerobic and resistance training, starting with thirty minutes of rowing machine and treadmill, followed by crunches and weights. It feels pretty good to have done it.

After working out we generally spend a few minutes with my sweetie’s folks, then we drive home. I’d estimate it’s at least half an hour between the end of the workout and our arrival home. Each time, on the way up the stairs to our apartment, I get a massive head rush.

Anyone know what’s causing it? Should I worry? When I was younger I had low blood pressure, but last time it was measured my blood pressure was on the high side. I haven’t lost a significant amount of weight, but I think I’m in better shape.

Any insight or wacky theories are welcome. Thanks!
