Precautions When Doing Planks
Avoid performing planks if you have a shoulder injury. Cease the exercise immediately if you experience shoulder pain. During pregnancy, planks are generally safe for many individuals, although there might be concerns regarding added pressure on the abdominal wall. Consider modifying the plank by opting for a side plank or an incline plank instead. Consulting with your doctor or a physical therapist can help determine if these modified exercises are suitable for you.
