Which is better for building strength? Weights or Resistance Bands?

Some people are either or people. I believe both have benefits for improving bone health.

When you add resistance to your routine, your muscles release calcium, magnesium, and other minerals that strengthen your bones. Your muscles don’t know whether the resistance comes from bands or weights.  Whatever you are more prone actually to do, that is the mode of choice. If you dislike weights, go for bands.
I personally like mixing things up.

Here’s the thing, though, you need to really challenge yourself for change to occur.

With resistance training, it’s too light if you can breeze through 20 reps of an overhead press. You’re building endurance, not strength. You should feel “worked” after 10-12 reps at a given resistance (whether it be weights or bands) with excellent alignment and good breathing technique.

I tell Pilates teachers to load up the springs on the Reformer for leg work for their clients with osteoporosis. If the springs aren’t heavy enough, they won’t gain strength or bone. (of course, ensuring proper form)

The other thing to remember is that your bone health is not only a reflection of your exercise. It’s also a function of your nutrition, supplementation, daily activities, or lack of…it’s difficult to tease out.

I believe your best shot at optimal bone health is doing weight-bearing resistance and impact exercises, dancing, walking/hiking, sports you enjoy AND also addressing other factors in your life that support bone health. When appropriate, medications may be the right choice.

Most people want a multifactorial approach to their bone health. I get that. In many ways, we are our own laboratory.

I want to share this interesting study from researchers at the U. of Oregon demonstrating how training with resistance bands increases bone mineral density.

“It is sometimes difficult for sedentary people to change their habits, and going to a gym would be more difficult. But elastic bands offer an interesting alternative since they allow enough intensity to stimulate bone mass, and a multitude of exercises are possible. Regular practice of 2 weekly sessions involving work on the main muscle groups of the body will increase bone mineral density.”  Here’s the research study
