Last night I donated blood. This was the first time in over a year.
This morning I did my usual circuits session in the gym. Just after the halfway point, I started to get a little dizzy. Then my vision started to go.
I can confidently say that I found my limit this morning.
Interestingly, my heart rate (according to my Fitbit) didn't reach the peak zone. It was actually quite low at the time I stopped and lay down.Go Top
