The lowdown

Rhabdomyolysis—rhabdo for short—is a potentially fatal but rare pathologic condition in which toxic intracellular constituents are released into the bloodstream from damaged muscle. It’s often caused by direct traumatic injury, but just about anything that results in extreme muscle damage can lead to it.

While it is considered rare, there is a rising number of cases reporting exercise-induced rhabdo, particularly concerning first-time spin class participants due to the exercise’s high-intensity nature. According to a study, these first-timers then experienced myalgia, muscle weakness, and dark tea-colored urine within a week of their first spin sessions—all of which are warning signs for rhabdo.

That being said, beginners aren’t the only ones who are at risk, but professional athletes are as well if they push themselves past their breaking points. As mentioned, the warning signs are myalgia, muscle weakness, and dark tea-colored urine. Pay attention to your body and note if the muscle soreness and swelling lasts more than a few days following an intense workout. After that point, seek medical attention in order to get treated immediately.

Just remember to not push yourself beyond safe limits. In other words, pay attention to your body to know when and where to quit. And if you’re coming out of a sedentary lifestyle by trying out a new fitness class, remember to take it slow. Don’t expect to be able to keep up with your instructor on your first try. Your instructor may encourage you to pick up the pace, but your safety should be your primary concern. It’s also key to stay hydrated before, during, and after your workout, as well as to warm up beforehand, cool down after, and take regular breaks in between.
