4. Planks


Oh, the almighty plank! Who doesn’t love them, right? Planks are great not just for giving you great abs, but also great arms and a great core. The key is to keep your body in a straight line and focus on holding yourself up with your arms more than your abs.

Don’t push your torso up in the air like you’re in downward dog, but also don’t sink your abs down to the floor, which can hurt your back. Keep your body in a straight line as if you’re pushing against a wall in front of you. Hold each plank for at least 30 seconds and work up to a minute, increasing the time as much as you can from there. Do these at least three times or more for best results.
