I'm Morris Brossette, and this is the benefits of abdominal isometrics. Okay so the entire reason you have abs is to stabilize and protect your spine ok. In sport a strong solid core is used to prevent form and breakdown. Once your core starts to break down you start to have a lot of extra movements that causes you to work harder then you should. So I'm going to show you two simple exercises that you can do that are isometric abdominal exercises that's really going to give you a strong solid core. So you don't break down ok. So what we are going to do is get into this start position. You are going to be on the balls of your feet. Elbows are going to be directly underneath your shoulders. Hands in fists and when you look straight down you should be looking between your fists not behind ok. On the balls of the feet we are going to engage the quadriceps, the glutes and tighten the abs and hold this position. Okay. We want to hold that, try to see if you can hold that for about 30 seconds ok. Once you've established that you progress up to 45 seconds. You can progress up to 60. From there you can start adding in variations. You can add variations like a reach out, here ok. You can add a variation like a shoulder tap. The most important thing when you are doing an abdominal isometric exercise is that you don't feel anything in your low back. As soon as you feel your low back that's the sign that this is starting to shut down and you can't support your spine. so once you feel that shut the exercise down and rest.
