Crunches are a basic abdominal exercise that is great for beginners to start training their core. They help hit the "6-pack" region of the core. To start the exercise, you will lay on your back, with your legs and heels together, and knees bent about 90 degrees with feet on the floor. Your heels can be as close together as possible, which I find helps me focus more on the Abs. Your hand/arm position can adjust to increase or decrease the intensity with these positions: - hands on your hips - arms folded across your chest with hands on the opposite shoulder - hands up as if you were boxing - hands behind the back of your head, with fingers interlaced When you start this exercise, start by activating your abs and lifting your head, shoulders, and arms off the ground with your shoulder blades raised as far above the ground as possible. When you fully contract, or "Crunch", your abs, slowly lower your body back to start position. These can be done for many reps. To further increase the intensity of the Crunch, try these: 1. Just like starting position, except, you will lift your feet and legs off the ground with knees still bent about 90 degrees and leave your legs in this position while you do Crunches 2. Straighten your legs and keep them together, then lift them till your feet are about 6 inches above the ground. Maintain this position while doing Crunches. I call this style, "6-inch Crunches" 3. To increase intensity for the 6-inch Crunches, lift your legs and aim your feet at the sky/ceiling. While doing crunches in this position, you will also straighten your arms in front of your chest, with your hands and fingers pointed to your feet/toes, while attempting to touch your toes with each rep. This is what I call "Toe Touchers" 4. For a static hold of the Toe Toucher, you will maintain the Crunch of the Toe Toucher for a duration of time. I call this variant the "Dying Cockroach" Work hard. Improve yourself. Be the Hero. You got this.
