HELLO SUMMER!

And, hello muscles! In this post, I continue the discussion I began last month on the benefits of strength training as we grow older.

Exercise, and particularly strength training, is critical to maintaining bone health. We achieve peak bone mass during the first three decades of life, which then begins to decline over the rest of our lifespan. For women, the losses accelerate after the onset of menopause (O’Flaherty, 2000). Contributing factors to bone loss are a sedentary lifestyle, low calcium and vitamin D levels, and hormonal changes. As we age bone remodeling decreases in both sexes leading to a negative bone balance at specific critical sites (Rosen et al. 1994). A large part of the solution is weight training, which has been shown to effectively increase bone mineral density in the spine and hips of post-menopausal women (Zehnacker & Bemis-Dougherty, 2007). [More research is needed on the effects of resistance training on bone density in older men.]

To reverse bone loss combine resistance training (exercises such as squats, leg press, leg extension, hamstring curl, hip extension, back extension, bench press, shoulder press, biceps curl and triceps extension) with high impact activities (jumping, skipping, hopping, jogging). If you already have osteoporosis, or other joint issues, then choose walking, hiking, or low impact aerobic classes.

How much resistance training is needed to affect change? Try doing 2-3 sessions per week, of 5-6 different exercises for both upper and lower body, 2-3 sets of 8-12 repetitions (70-90% of 1 repetition maximum), which can be done in as little as 20 minutes. 

There’s no down side to adding in a few sessions per week. 😃  Increasing muscle mass equals better metabolism, better body composition, and better bones!

In closing, I offer you two new videos. The first video is the second in my 5 Essential Exercises series – The Push. I cover four of my favorite upper body exercises that just about anyone can do. The second video is a vinyasa yoga practice where I talk a bit about the fifth limb in Patanjali’s yoga system – Pratayahara (turning in).

May this summer find you thriving and well!
