core exercises
The buzz about working “core” muscles seems like it will never go away. First of all, most people don’t even know what the word “core” means. As a matter of fact neither do I! The word ‘core’ does not come from any scientific anatomy text I have ever read. As far as I can tell it is a term created by the fitness industry to promote all kinds of ab training products.

I’m assuming core training is supposed to give you a hard flat stomach or possibly even a 6 pack. I think this myth about core training is also how much of the new athletic style workouts are becoming popular as may exercises athletes do seem to appeal to the people who think they are doing a core exercise. So what is your core anyway?

As far as I can tell, people think their core is their abs, the oblique muscles (the muscle that are on either side of your middle set of abs) and your lower back muscles. This collection of muscles makes up the mythical “core”. Now, if anyone besides a graduate trained biomechanist tells you they know exactly how these muscles work, they are lying, and probably haven’t done enough research to know that they are lying (so technically its not really their fault for misleading you). The muscles of the core are very complex and the truth is that scientists still aren’t sure exactly how they all work together. So now that we can see we don’t really know how all the core muscles work together, how can you possibly think you are training them in any intelligent way!

The truth so far is that any exercise works your core muscles to some degree or another. As soon as you stand up and get out of bed in the morning your core muscles have to be activated to prevent you from just flopping over at the waist. All forms of rigorous physical activity will work your core muscles. For example, one of the toughest core workouts you can do is a series of short all out sprints. Don’t believe me? Give this sprint interval routine a try and see how sore your ‘core’ and ‘abs’ are the next day.

20 yard sprints x 4

40 yard sprints x 4

60 yard sprints x 4

80 yard sprints x 4

100 yard sprints x 4

After each sprint walk back to the start and repeat until you have completed 4 sprints at that distance, then take 90-120 second rest and start the next distance. If you push these hard, your whole body should be sore the next day including of those ‘core’ muscles. I’ll bet this is not the image you had in your head of a ‘core’ workout.

You can train ‘core’ muscles every day if you want, which isn’t saying much because they are working all the time anyway. With that said there are core exercises that are better than others, and the exercises people typically think of for core should not be performed every day, and some of them like crunches should never be done at all. In the second part of this article I will discuss the right and wrong way to train this part of your body.

Body Weight Workout

core exercises
Sprinting is a great way to improve cardiovascular, agility and build a leaner tighter body. It is also a tough workout and should only be done if your in really good to great shape. If you’re not at this time, you can jog throughout this workout and build up to sprinting. This should be done 2 days a week.

Set up 5 cones (or anything you have as a visible marker) 90 feet apart (don’t get technical with this, just walk 30 paces which is roughly 3 feet per pace). Beginning at your 1st cone (doesn’t matter which end, the first cone is always your starting point), sprint to the 2nd. Now walk to until you reach the last cone. Sprint to the second cone. Walk to the last cone. Sprint to the 3rd cone. Sprint to the 4th cone. Walk to the last cone. Sprint all five cones. Walk to the first cone turnaround and go back to the start line. Repeat exercise. Once if combining, 4 times if doing solo.

Sprint for 30 seconds. Now walk 90 seconds to 2 minutes. That’s one rep, start by doing 5, work your way up to 8.

As soon as your done with sprints, do these core exercises.

The workout – do each exercise for the designated reps. Do all five without a rest. Once completed, repeat entire circuit again

Weighted crunch – Lie on your back, knees bent, holding a plate on your chest. Slowly crunch up, bringing your shoulder blades off the floor. Pause, then return to start position. That’s one rep, do 10-15. Please note – if it’s too hard to do with a plate, just do regular crunches.

Pulse up – Lie with your hands under your tailbone and your legs extended straight up toward the ceiling. Lift your hips off the floor in a straight line, pause, then lower to start position. That’s one rep, do 10-15.

Side Jackknife – Lie on your left side, with your legs with your legs nearly straight and slightly raised off the floor. Also lift your left torso off the floor, with your left forearm on the floor for balance. Hold your other hand behind your right ear, with your elbow pointed below your feet. Lift your legs toward your torso while keeping your torso stationary. Pause, slowly lower your legs to the start position. That’s one rep. Do 10-15, then switch sides.

Negative crunch – sit with your knees bent and your feet flat on the floor, shoulder width apart. Extend your arms in front of you with your fingers interlaced. Begin with your upper body at slightly less than a 90 degree angle to the floor. Lower your upper body toward the floor, curling your torso forward, rounding your lower back and keeping you abs contracted. When your upper body reaches a 45 degree angle to the floor, return to the start position. That’s one rep. Do 10-15
