Lifting heavy weights will improve your bone density.
A lot of the recommendations for “heavy weights” means above 80 percent of your max. To put it simply, that’s what you can lift for 6 reps or less.
It places a high mechanical load on the bone and signals your body to build stronger, denser bones. This is especially important for menopausal women and anyone wanting to age with strength and independence.
But, you can’t walk into the gym on day one and lift that heavy.
Even if your goal was to become the strongest powerlifter on the planet, I would never start you at 80 percent.
To lift heavy safely and effectively, you first need to:
• Learn how to lift with proper technique
• Build work capacity
• Build muscle and prepare your joints and connective tissues for higher loads
Lifting heavy is one of the best things you can do for bone health and longevity. But there is a process to earn the right to go heavy.
