The basic sit up technique is quite simple, it begins with lying with the back on the floor, typically with the arms across the chest or hands behind the head and the knees bent in an attempt to reduce stress on the back muscles and spine, and then elevating both the upper and lower vertebrae from the floor until everything superior to the buttocks is not touching the ground.. The main key is to make this a controlled and contracted movement. Flex your abs at the top of each motion and don’t just rush through the reps.
You can complete the number of repetitions over a series of sets or over different time periods through out the day. Complete 20 before morning shower and take a break, then after lunch or before bed time you can complete another set of 20 until you have completed all the reps for that day. However, consult with a doctor before starting any new exercise routine. Start now and help inspire others to workout and get in shape!
