Maybe you’ve seen your friends Facebook photos of them planking in strange and sometimes dangerous places. Planking is a great core exercise, but this student took it a little too far! If you have never planked before, you can check out the exercise here. An improper plank even on a flat surface can injure your back. I strongly recommend that you ask your NJ Personal Trainer on the proper way to plank. If you have any personal training questions you can visit our website or email me at firstname.lastname@example.org.
