The wonderful advantage of doing the plank exercise is that it helps to build your strength and endurance, which is important for those who run on a daily basis and/or preparing for a marathon.

• Lie down on the floor on your stomach.
• Extend both of your arms ahead of you, as well as both of your legs behind you to prop up your body.
• Hold this position for 60 seconds.
• Rest for 30 seconds. Repeat for another 1 to 2 reps.

The plank is a great warm-up exercise that heightens your endurance and strengthens your core. Take care not to collapse your lower back, and remember to breathe!
