5 Abs Workout from healthkicker.com

I have been browsing through some fitness websites and I found a neat one: Healthkicker. com It has a comprehensive database on work out instructions. Worth a look! 

Here are some exercises I found that would strengthen your abs!

V-Up 

1. Start position: Lie back onto floor or bench with knees bent and hands extended towards ceiling. Head should be in a neutral position with a space between chin and chest.
2. Leading with the chin and chest towards the ceiling, contract the abdominal and raise shoulders off floor or bench. Also raise legs up towards ceiling and attempt to touch your hands to your feet. 
3. Return to start position.
   

Alternating Toe Touch

1. Start position: Lie back onto floor or bench with feet up into the air. Head should be in a neutral position with a space between chin and chest.
2. Leading with the chin and chest towards the ceiling, contract the abdominal and raise shoulders off floor or bench. Extend one arm and reach for the opposite foot. Return to start position and repeat with other hand.
3. Remember to keep head and back in a neutral position. Hyperextension or flexion may cause injury. To increase resistance, hold medicine ball in hands. To decrease resistance, position hand closer towards body

Plank 

1. Start by placing your forearms on the ground and forming a plank with your forearms and feet.
2. Hold this position keeping your body parallel to the ground for the required time.

Burpees

1. From a standing position, jump as high as possible and land down on your feet with your hands on the ground. 
2. Kick your feet back. For a moment you will be in a push up position and jump back up again as fast as possible.
3. Repeat for the required repetitions.

Supine Double Leg Raise

1. Start by lying on your back and a slight bend in your knees.
2. Raise your legs to a perpendicular position to the floor. This is your starting position.
3. Slowly lower your legs until you are no longer able to keep your abs tight and your low back on the floor. 
4. Raise your legs back up to the starting position and repeat. 
5. Only lower your legs as far as your abs have enough strength for.
