Never too late! Older people over 50+ need strength training even more than younger people. Our muscles and bones start to detioriate at a much faster rate but we can reversre the process pretty easily with a good strength training program.
Strength is the FINAL way we interact with our environment. A good strength trianing program can double your strength in less than 3 months or triple your strength in less than 6 months. Being stronger just makes everything in life easier.
If you could clone yourself and your clone was 3x stronger than you , who would have more energy at the end of the day? Who would have better perormance on the pickleball court wtih a less chance of being inured? Who could handle daily chores easier? Pretty much your clone would dominate you in all aspects of life.
