You have the ability to burn calories up to 48 hours after the workout. What does the mean? It means burning calories even when you are not working out. Now how cool is that?
Being able to maintain your lean muscle mass is very important when you get older.
Every decade after the age of 30 you lose 3 to 5% lean muscle mass loss. The only way to combat that lean muscle mass decline is lifestyle change….
So you need to make sure you are consistent with weekly resistance training. Weight-training is not optional it is mandatory for optimal health.

The more lean muscle mass you have the faster your metabolism will be.
Women should weight-train even more than the guys because they are more prone to Osteoporosis than men. 1 in 3 women over the age of 50 will obtain osteoporosis.
And the best way to combat the decline of bone density is weight-training.

Women you are not going to look like Lou Ferrigno or Arnold Schwarzenegger if you lift weights because you don’t produce enough testosterone as a man.
The only way is if you started to take steroids then you would start to look manly….LOL
There was a research study that was done in 2016 at UCLA and the result was that the higher lean muscle mass and lower body fat composition you have the lower the risk of death for people with heart disease.

Here is the research below to that UCLA Study:
