Your Shortcut To A Stronger Core
Check your plank account: long holds are not the best option
If you know someone who boasts about how long they can hold a plank position, tell them new research shows longer is not better. The study1 found that prolonged holds can reduce muscle oxygenation in the core muscles. This has been linked to the development of lower back pain and for this reason the researchers recommend you limit the duration of each plank to 30 seconds. Do several reps or try harder variations of the exercise to keep it challenging.
