5 META-ANALYSES ON EXERCISE & BONE

WALKING HELPS HEALTH. LOADING HELPS BONE.

If your goal is to preserve bone, do not hang your hat on walking alone. Lift. Do weight-bearing work. Better yet, combine them. Across 5 meta-analyses and network meta-analyses in peri/postmenopausal or postmenopausal women, the pattern is pretty consistent: resistance training helps, weight-bearing loading helps, mixed programmes often do best, and walking alone is a weaker primary option if bone is the target.

This is not one cherry-picked study. These papers together include 257 studies or trials and at least 16,943 women. That total is a summed total across reviews, not a unique headcount, so there is overlap between papers.

My read of the evidence is simple. Resistance training should be the anchor. Add weight-bearing or impact work if appropriate. Multimodal training keeps floating to the top.

Walking is good for health, but if bone is the actual goal, it is usually not enough on its own. And this is a months-to-a-year adaptation, not a 2-week project.

If bone is the target, walking is a start, not a finish line!

P.S. Adequate calcium, vitamin D, and protein (1.6 g/kg/d or less) and in that order, are also a big part of supporting this.

Turning Back Time: Moving Like a 20-Year-Old When You're Almost 70!

Older adults can maintain youth-like levels of physical function—if they lift weights. A new study compared older adults (~69 yr) who resistance trained to young adults (~24 yrs) who did not. The result? On key measures like:

• Chair-stand performance
• 6-minute walk test
• Timed up-and-go

➡️ Older lifters performed as well as (or better than) young non-lifters.
No gimmicks.
No biohacks.
No pre-exercise protein.
No creatine.
No fancy pixie dust…
Just consistency and resistance training—2x/week following ACSM guidelines. How simple is that?

Flip the script on aging: muscle loss and functional decline aren't inevitable. Resistance training is powerful, accessible, and proven to maintain independence and quality of life as we age.

Older adults can maintain youth-like levels of physical function—if they engage in weightlifting.

We observed a rather uniform skeletal response to the menopausal transition at all measured bone sites. Positive associations were found between medium and high-intensity impacts and bone characteristics at the femoral and tibial shafts. However, habitual skeletal loading did not seem to counteract....

There's a tendency for women to lift light weights for high repetitions, like picking up five-pound dumbbells and lifting them 20 times. This is often called "body sculpting" by trainers, who promise women that they can "tone up" without "getting bulky muscles." This mindset needs to go because it's misleading, misguided, and honestly not helpful for women whose s*x hormones, lean muscle mass, and strength are on a precipitous decline in perimenopause. This type of lifting will build muscle endurance, but that's not what you're looking for at this stage of the game. You need muscle STRENGTH.

Background About 20–30% of older adults (≥ 65 years old) experience one or more falls each year, and falls are associated with substantial burden to the health care system, individuals, and families from resulting injuries, fractures, and reduced functioning and quality of life. Many intervent...

We've been chatting a little bit in some classes about how the hips respond to Onero - Belinda goes into some details here, around the 17 minute mark which may be of interest. Some interesting information in here, especially first half of the interview. Have a listen!

Just because you have Osteoporosis doesn’t mean you can no longer lead an active lifestyle or you have to stay indoors to minimize the risk of falls and frac...

Here's Marilyn, one of our fantastic clients raising awareness of osteoporosis on the news last week. Keep an ear out for a little plug for Bone Fit right at the end 🙌💪
Thanks Marilyn!

Most of us think that aerobic exercise (swimming, cycling...anything that gets your heart rate up for a while) is the best way to reduce blood pressure. Turns out...not! Resistance training (like Onero) is more effective than aerobic exercise, a combination of the 2 is better still, and, biggest surprise of all, isometric exercise is best! Weird. The take home for all our Onero devotees is that you're getting bonus benefit for your blood pressure. 🙌🤛💪 https://pubmed.ncbi.nlm.nih.gov/37491419/
