Review: excellent book; good selection of exercises Review: I am in my upper 60s, and except for walking a lot, I am exercise averse. Never enjoyed exercise. Never actually felt better after exercise. To the extent I have exercised it was to achieve a goal, e.g., getting in shape to go on a kayaking trip. Well, you see I don't think of kayaking as exercising, I think of it as getting into places I could not otherwise go. So, I am not in great shape but I am thin. I give you this background information only to help you determine if this is a good book for you. There are many levels of exercises in this book and many different exercises at each level. You can choose between equipment free exercises and some minimal equipment exercises, e.g., using a balance ball. I started at the very lowest level with the lowest intensity and without any equipment. I did not expect much. The book told me not to expect too much too soon. But I knew I needed to strengthen my core and whatever I tried before was too hard and/or painful, e.g., pilates. No level of pilates seemed doable given my generally weak core. Mostly, my pot belly, in spite of the fact that I am thin, spoke to me and said I had to do something. I found this book quite by accident. The author's book on stretching for 50+ was advertised in my Tufts Nutrition Newsletter and I have found the books they advertise/recommend to be very helpful. Anyway to cut to the chase. I went out to do an hour's worth of yard clean up this weekend, which generally involves quite a bit of heavy lifting and this weekend was no exception. I expected to be in pain the next day as usual. I was not in the least bit of pain the next day. None. I can only attribute that to 12 days with this book using the lowest level, lowest intensity of exercise. Nothing else has changed. I also feel that I can carry significantly more weight. In addition I do not hate doing the exercises. I am very happy with this book. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | 1612431011 | | Customer reviews | 4.5 4.5 out of 5 stars (384) | | Dimensions | 19.05 x 0.74 x 23.5 cm | | Edition | Illustrated | | ISBN-10 | 9781612431017 | | ISBN-13 | 978-1612431017 | | Item weight | 272 g | | Language | English | | Print length | 144 pages | | Publication date | 6 September 2012 | | Publisher | Ulysses Press | ## Images ![Core Strength For 50+: A Customized Program for Safely Toning Ab, Back, and Oblique Muscles - Image 1](https://m.media-amazon.com/images/I/71O3ua76uyL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***D on 19 July 2025* excellent book; good selection of exercises ### ⭐⭐⭐⭐⭐ Review *by C***T on 28 May 2013* I am in my upper 60s, and except for walking a lot, I am exercise averse.

Core strength is even more important for seniors and this little book is a good introduction to the subject. Figures are adeguate and clear enough. I might have liked it to go deeper, but I still recomend it to the novice as a useful introduction to safe core strength training by seniors. ## Frequently Bought Together - Core Strength for 50+: A Customized Program for Safely Toning Ab, Back, and Oblique Muscles - Stretching for 50+: A Customized Program for Increasing Flexibility, Avoiding Injury and Enjoying an Active Lifestyle - Weights for 50+: Building Strength, Staying Healthy and Enjoying an Active Lifestyle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/306709194-core-strength-for-50-a-customized-program-for-safely-toning](https://www.desertcart.kr/products/306709194-core-strength-for-50-a-customized-program-for-safely-toning) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-21*
