It’s been nearly 30 years since the scientific community first developed a serious interest in exploring the interactions between the bugs in our guts and the neurons in our brains. Researchers have since demonstrated how psychological states can trigger gastrointestinal disorders while also showing how dietary decisions — and their impact on the microbial mix in the gut — can affect neurological function. So I guess it was only a matter of time before they would wake up and smell the coffee.

Divide the reps and distances between partners to enable constant movement for the duration of the workout. When one is working, the other rests. (For instance, you might switch off every 20 lunges, every five burpees, every 10 thrusters, or every 250 meters of a run.) Note how long it takes to complete the workout. Complete the 0.62-mile run on a track or treadmill. Complete the 0.62-mile run on a track or treadmill. Complete the 0.62-mile run on a track or treadmill.

Otherwise, your midsection will rock from side to side as you struggle to stay rooted in place.
