This 4-Week Core Challenge Is Perfect For Beginners

• Starting from a seated position, extend your legs out in front of you and place your hands on the floor, slightly behind your body and above six inches away from your hips, with your fingertips facing in the same direction as your legs.
• Keeping the form solid, lift the legs and then tuck the knees back towards the chest. Avoid excessively rounding the back and relying on putting emphasis on the neck. Return to your starting position. That's one rep.

Note: This exercise does not necessarily need any extra equipment, but if you have access to a bench, this would be a good progression. These can be performed on the floor, on a yoga mat, or on the edge of a bench.
