DID YOU KNOW: If you think you’re too old or too out of shape to lift weights, think again. It is never too late to start. People have successfully started strength training in their 70s, 80s, and even 90s with positive results. The same goes for people who are overweight, inactive, and fatigued. Start slow and conservatively. There is definitely no such thing as being too old or too out of shape to benefit.
