Weekend Challenge: Seated Abs And Legs Strengthener - Save Our Bones

I hope that all Savers who celebrated Thanksgiving had a wonderful holiday.

Now that we’re in the post-holiday weekend, I’m looking forward to getting back into exercising for my bones. I’m sure you’re ready, too, so I’m thrilled to bring you this weekend’s challenge: the Seated Abs And Legs Strengthener.

As the name indicates, you can do this exercise while sitting down, which makes it all the more convenient and accessible. It works the abdominals, core muscles, and legs, and we’re going to start by looking at why these areas are important in the fight against osteoporosis, including a new study on the benefits of trunk strength in older adults.

So read on and enjoy today’s exercise! You won’t even need to get up from your chair…


Trunk strength is of particular importance as we age, as we’ll see when we look at the research in a moment. A strong trunk includes the muscles of the core, back, hips, sides, and abdominals – pretty much your entire torso. Strong trunk muscles improve balance and posture, and working them boosts bone strength in the ribs, spine, and hips.

Today’s exercise also works the legs, further strengthening the hips and thighs. Preventing fractures in the hips and femur it of utmost importance, and this exercise targets these areas.

Let’s take a closer look at these muscles and the bones they strengthen, beginning with the trunk.

The abdominals encompass the muscles of your sides, back, and stomach, so they cover a significant area. These include:

  • The obliques, which run along your sides and attach to your pelvic bones and ribs;
  • The tansverse abdominus, which are deep core muscles that lie under the obliques and stabilize the pelvis and spine;
  • The rectus abdominus, which is at the front of your torso (your “tummy muscles”); and,
  • The multifidus, a muscle which lies deep in the back and connects to the lumbar vertebrae in a sort of zigzag pattern.

All of these muscles attach to bones, of course, and according to Wolff’s Law, working the muscles stimulates growth and density in the bones they attach to. The bones of the torso area include the ribs, pelvis, and thoracic and lumbar vertebrae.

Savers are well aware that density and tensile strength in these bones are paramount to preventing fracture, either from falling or compression.

The Seated Abs And Leg Strengthener also works the muscles of the legs, particularly the quadriceps, adductors, and abductors.

The quadriceps, or quads, are four-part muscles on the front of your thigh. Strong quads stabilize the knee joint, strengthen the femur, and promote balance.

The adductors move your leg inward toward the middle of the body, while the abductors move the legs outward, away from your body. In today’s exercise, you’ll be doing both, giving your upper legs a well-rounded workout.

And finally, today’s exercise works the hip flexors, aka the iliopsoas muscles, which attach at the top of the femur. They originate at the base of the spine and pelvis, and they’re an important muscle group that is crucial for balance and spinal alignment.

The bone that’s primarily targeted by this move is the femur. While this is one of the strongest bones in the human body, it’s prone to fracture if you’ve ever taken osteoporosis drugs. Ironically, bisphosphonates raise the risk of femur fracture, particularly in the femoral neck.

So have a seat, and let’s get started on strengthening these bones and muscles.


All you need for this exercise is a chair.

  1. Sit up straight in your chair and place your hands on the sides of it.
  2. Stretch your legs forward, keeping your knees straight, heels on the floor, and toes facing up.
  3. Bend one leg toward your chest, and then back to the starting position, alternating legs each time. Repeat about 20 times, or as many times as you comfortably can.
  4. Rest one minute and repeat the set three to five times.

I like to follow this exercise with the Seated Core And Oblique Strengthener because it also focuses on the trunk and torso muscles. And that’s important, because the latest research points to trunk strength as pivotal in combating issues specific to older adults.

Study Highlights The Benefits Of Trunk Strength In Balance, Fall Prevention, And Daily Activities

As the number of older adults in Western society increases, so does the incidence of falls and fractures associated with aging. In light of this, scientists are looking closely at ways to counteract the effects of aging, and a 2013 review of the data reveals some fascinating facts.

The evidence clearly points to core strength exercises as “significantly” enhancing trunk strength and spinal mobility, as well as reducing lower back pain. In fact, the researchers note that core strength training has been established as “an effective means of treating chronic low back pain.”1

The report goes on to explore the importance of trunk and core exercises in enhancing balance, preventing falls (especially by increasing the effectiveness of “corrective” movements in case of balance loss), and promoting better use of the upper and lower extremities.

And last but not least, researchers report that a strong trunk improves quality of life and daily activities:

“…exercises that have the potential to promote appropriate dorsal (e.g., multifidus, erector spinae) and ventral (e.g., transversus abdominis, internal obliques) muscle responses may improve performance of activities of daily living due to enhanced [trunk muscle strength] and core stability.1

Once again, regular, targeted exercise provides benefits that go beyond improving bone health. In the Densercise™ Epidensity Training System, you’ll find many core and trunk-strengthening exercises in addition to other moves that focus on fracture-prone areas like wrists, ankles, and hips.

Densercise™ only takes 15 minutes, three times a week, yet its 52 moves are challenging, highly-effective, targeted exercise specifically designed to build bone density, enhance balance, improve coordination, and much more.

    Just had a question. I do most of these execises in the pool. Is this just as affective as doing them on land?

    • Vivian Goldschmidt, MA

      That’s a great question, Pam. While exercising in water does not provide the benefits of weight-bearing exercise, it has benefits of its own. For example, the water offers resistance, and moving in the water increases joint range of motion. Water exercise is helpful for those who have trouble balancing. However, it’s important to be aware that the benefits of doing exercises in water will not be the same as doing them on land. You can read more about this topic here:

    I, too, wish I could obtain your exercise books in print. The digital form is great for showing how to do the moves, but it’s not easy to set up the right environment around the computer to perform the exercises. Because these days it’s easy to produce books on demand without great cost, why not consider providing the books at whatever cost seems right so that hundreds of us can reap the benefit of your incredible knowledge, easy to understand explanations, and excellent exercises.

    Vivian –
    You made such a difference in my life! Thank you for your dedication to the “cause” – making me – and all of us who were ever duped into taking biophosphanates – for our own “good” of course – because we “needed” this stuff – to get our lives back.
    It’s taken me almost 10 years after refusing to take Actonel any more to achieve some level of normalcy.
    My leg strength today comes from walking a Jack Russell terrier – he is a rescue dog – and thank heaven he loves to walk and needs to walk. As is in so many things in life, all it takes is a little bit every day – you build up your strength over time, a little at a time, day-by-day, and then one day you realize your strength is back. I look forward to your advice every time I receive one of your emails.

    • Vivian Goldschmidt, MA

      Believe me, “Florida Girl,” you and all the Saver community have made such a difference in my life as well! Your dedication and determination to stay the course are admirable. Thank you for sharing and encouraging others, and congratulations on your rescue dog! It sounds like the benefits work for both of you. 🙂

  4. Sharon

    Thanks for the seated moves, at 71 I walk a couple miles daily, and do my exercises
    four times a week . I feel darn good!!!!

    • Vivian Goldschmidt, MA

      Good to hear, Sharon! 😀

  5. Bon

    I am ( will b 73 in Jan). I am experiencing pain in my lower legs when I walk. It may be from different shoes. If I start your “save my bones ” program will it heal/ reverse any damage already done? I had two rib fractures this year have had several last 9 years. I took fosomax only 3 months many years ago I refused to take any drugs after researching what they cause. I don’t like going to doctors because they only know two things: 1.. Prescribe poisonous BIG PHARMCO drugs. Or
    2. CUT ( surgery). On you
    They do not pride themselves on DIAGNOSING !! They never consider….. How did doctors diagnose BEFORE all this money making testing equipment ! After all the test they still have no clue what is wrong with your body !!!! I LIVE IN THIS BODY and when it isn’t working properly I can do as well or better than the DR IF I read and research. After all that is what they do
    My prescription: leave their poisonous drugs for THEM to swallow …. CONSUME what GOD gave to us (the leaves of the trees for the healing of the nations) HERBS ( PURE) organic foods….THEN… ALLOW. YOUR MAGNIFICENT GOD MADE SELF HEALING BODY TO HEAL!
    Love u Vivian

    • Vivian Goldschmidt, MA

      I love your attitude and your “prescription,” Bon! If you decide to try the Program, remember it’s more about your personal “bone health philosophy” than whether or not following the Program will “fix” any particular health concern. It sounds like you already have your philosophy well underway!

    I am nearing 80. Can walk ok, but need a cane to go up and down the stairs. Can do only sitting-on-chair exercises. I do chait yoga. Thanks so much for the simple chair exercises that suit me well and make me happy.
