Increase the Weight. Keep the System.

The Strength Shop Extension Kits allow you to upgrade your existing Adjustable Dumbbells to a higher weight range — without replacing the handles or starting from scratch.

Each kit includes precisely the components required to reach the next configuration. The adjustment mechanism, balance, and feel remain exactly the same: only the maximum capacity increases.

All kits are fully compatible with the Strength Shop Adjustable Dumbbell system.

  • 20 kg to 49 kg – Increases a 20 kg dumbbell pair set up to a 49 kg set (Contents: 28 × 2 kg plates, 2 × pair of long bolts 1.5 kg)
  • 36 kg to 65 kg – Increases a 36 kg dumbbell pair set up to a 65 kg set (Contents: 28 × 2 kg plates, 2 × pair of long bolts 1.5 kg)

  • Maintain identical handling and balance
  • Save space and cost compared to buying a second set
  • The system is built to grow with you

FAQs

  • Q: Do I need to buy a completely new dumbbell set to increase the weight?
    No. The extension kits are designed specifically to upgrade your existing Adjustable Dumbbells.

  • Q: Are the plates identical to the original ones?
    Yes. The extension plates match the original plates in material, dimensions, and finish.
  • Q: Do the kits include handles?
    No. The extension kits include only the listed weight plates required for the upgrade.
  • Q: What is the weight range for the different bolt configurations?
    The dumbbells can use two bolt configurations depending on the total weight:

    Standard bolt (1 kg): adjustable from 4 kg up to 36 kg
    Extended bolt (1.5 kg): adjustable from 39 kg up to 65 kg

A must read for Adult Survivors of childhood Emotional abuse
Format: Paperback
A definite must read especially if you have difficult family relationships. My childhood was very unhappy and confusing as I had a mother who is a borderline. My father, who seemed to be the anchor of reason in our family, recently passed causing some very difficult and seemingly unreasonable discussions. My mother was all over the place emotionally, causing me as an adult many sleepless nights from her verbal vomits. This book really gave me renewed courage and strength to find and hold my ground and feel right about setting boundaries for myself. As a survivor of a borderline, it is very difficult to have good healthy relationships with your own children because even years after you’ve left home and have your own family, those words “I hate you, I wish you’d never been born” can still come to haunt you and cause you to doubt yourself. I gave a copy of this book to my sisters. One read it, and both she and her husband devoured it. It really has helped us to separate ourselves from some of the family crazy, and be more Christ centered and ministry focused. Our mother was quite good at throwing “bible” at us and using it rather inappropriately to fit her agendas, always causing us to doubt our effectiveness in ministering your other individuals.

Most Helpful Book. Taught me a lot about myself too.
Format: Paperback
I purchased this book in an effort to make sense of a toxic family member. This book was so helpful for that but also helpful in teaching me how to respond and not become toxic myself.

Healthy
Format: Kindle
Informative and full of insight. It helped me to see there is a difference between a difficult person and a toxic one. Also the danger of labeling, name calling and toxicity.
