Warm-up: Light stretching. Here is a new 5 minute stretching video. Only do what you are comfortable with. https://www.youtube.com/
*30 minute cardio. 6 rounds of 1 minute walk, 4 minute jog. Commit to doing this workout 3 to 4 times a week.
*4rds, 25-air squats, 12-push-ups, 25-sit-ups. Modify as needed.
Air squats-find something to put under you bottom as a guide for how far to go down to. Make sure it is a comfortable depth, not too far down.https://www.youtube.com/
Push-ups-you can do them from your knees or even standing
against a wall. https://www.youtube.com/
Sit-ups- Feel free to do crunches. DO NOT place hands behind your head. That only puts undue pressure on your neck.
