Dennis Albright: Hi, I am Dennis, this is Charlotte and Michelle. We are from Performance Private Training here in Colombia, Maryland. Today, we are going to talk to you about strengthening your core muscles. Today's video is going to cover a plank which is a core strengthening exercise.

We are going to talk about some safety measures to look at during the plank. We are also going to talk about different variations of a plank. Whether to use a side plank and using a rotation using a side plank as well as using weights. We are also going to talk about using a stability ball or swiss ball while performing a plank. The last thing that we are going to discuss is talking about a really good stretch afterwards.

Some tools that you would need to perform the plank would be a mat, a stability ball or swiss ball or you could use a water ball or a weight, 3-5 pound weight. As always, make sure that you have a physician's clearance before performing any of these exercises. Between the three of us, we have 26 years of experience. In Performance Private Training, we offer memberships as well as group training from studio cycling to Cardio Kickboxing as well as personal training alone. Let's start today by performing a basic plank.
