I do mine on my exercise ball. I lie over the ball with my hands on the floor and then roll forward until my knees are on top of the ball and hold them there for a count of 10. I do several reps. It doesn't hurt my neck at all, but seems to give my abs a good workout.

My DD has a Ab Tilt. Just sit with your back against the backrest, grab the handles and bend forward. You can also twist to each side while pulling the handles. There may be other ways to utilize it, but I can't find her manual either. :-)

Unfortunately, I am very lax on exercising... I used to go to the pool and exercise when I lived in former town, but it got to the place the chemicals made me itch and break out so badly that my skin bled... I walked 3-4 miles a day...then came 3 joint replacements and arthritis in every joint in my body and I have constant pain. The surgeon who relpaced one of my hips, cut the nerves and I walk with a terrible wabble and it feels like it is caving in with each step, and no fixing it...the nerves are dead....so makes my back hurt and have terrible balance when I do try to walk. I have gained a lot of weight and it know it makes all of my health problems worse..plus I am blessed with tremors in my hands..so I think I have just given up on extending my years. I am able to keep up with my house and take care of my personal needs, but life has lost its "fun" for me any more.

I'm a personal trainer. If you can afford it, find a good personal trainer to get you started. Form is very important. With good form you are working your muscles optimally and preventing injury. You also need to be in front of a mirror so you can make sure your in form. Weight/strength training is very important as we age. It makes daily functional movement possible. It gives us the strength to get up off a chair without holding on to the arms, bend to pick something up, reach to get something off a shelf, etc I know to many it's boring. That's why you need to change routines frequently. Utube, Pinterest, and Instagram are good resources. If your starting out, look for instructors showing functional training. These should be basic exercises. Make sure you do these in front of a mirror! Remember this: Cardio burns calories, weight training burns fat. With this in mind, you can get a very good work out in 1 hour. Cardio for 20 m-1/2 hour followed by weight/strength training. Your heart rate will still be up. Xertubes and bands are also good to use. Some come with tapes or you can find exercises online. They can be purchased at Dicks or online I like Spri and Power Systems as vendors Gosh, I can go on and on here lol
