We are all looking for great core exercises, and we know that the plank is a go to.  If you are looking to up the intensity of your plank you can try weighted planks, which are simply standard planks done with weight on your back.  Use caution as you need to ensure that you keep your back straight despite having added weight. Start off with a 5 lb plate and then eventually progress to 10 lbs. The plate should be in the middle of your back, not on your upper back or on your lower back. Hold for a minute and complete 3-4 times. Your core will thank you the next day!
