Lets keep the exercises rolling. Already discussed the importance of the plan and why people need to do it. Not only is it one of the best ways to hit your entire core and those hard to rich lower ab areas but it also helps stabilize the spine for better posture and less back pain. Just make sure that if you dip your hips you stop because that is your breaking point and you are no longer doing the exercise correctly when that happens.
There are many variations to the plank, all will work your body hard enough to give you a 6 pack in 6 weeks if done every other day. One great variation is a circuit of the three. Start on both arms and after 30 seconds rotate to one side and proceed with 30 seconds on that side. Then drop back to the middle on both arms for 30 seconds and then on to the other side. That is one set. After 2 sets of that you will be burning. Continue to build on this with either more sets or increasing the time. The goal should be to hit 2 minutes and by that time you will be a pro. Stay tune for more variations and take your fitness All the Way!
