Lactate threshold plays a significant role in how much aerobic potential you are tapping. It can be defined as:

“The point during exercise of increasing intensity at which blood lactate begins to accumulate above resting levels, where lactate clearance is no longer able to keep up with lactate production.”

During low intensity exercise, blood lactate remains at or near resting levels. As exercise intensity increases (CrossFit) there comes a break point where blood lactate levels rise sharply. Researchers in the past have suggested that this signifies a significant shift from predominantly aerobic metabolism to predominantly anaerobic energy production.

In CrossFit, whether it be the sport or fitness routine, ones lactate threshold is extremely important. The bodies ability to be more efficient in lactate clearance means better performance. One of the best ways to work lactate threshold is with rowing and running repeats. They are simple, and very effective.  

No matter your level of CrossFit ability, doing these types of workouts will help your body run more efficiently. Isn’t that a primary goal of fitness? Choosing to do workouts like today’s will not only make you more fit but will increase your bodies aerobic potential. I encourage everyone to take these days seriously and have fun!
