So while you can’t necessarily beat the heat, you can deal with it. One way? Make your workouts shorter and more intense. We’re not talking total intensity here; just a minute or so popped into the slow. For instance, jog five minutes, then run for one minute like you’re chasing an ice-cream truck. Repeat a time or two.
That’s how I’ve been swimming lately. Instead of swimming continuously, I’ll swim up and down the lane 10 times at a happily poky pace, rest a minute, then go as fast as I can up and back. Rest another minute and repeat maybe three or four times.
