Is it possible for someone in their 40s, 50s, or even 60s to look (and even feel) like they’re in their 20s or 30s? If it is possible, how can it be done?

I’m almost 55. I took this picture yesterday at Jones Beach field 6. I plan on keeping this body for many years to come.

Edit: I forgot to include how.

I do 4–5 sets on every bodypart with extreme intensity and to complete muscle failure. I hit all angles, but not always on the same workout. Repeat every 3–4 days. 45 minute workout including cardio. It’s not about the amount of time spent in the gym. It’s the intensity. I eat 10-20g complete protein every couple of hours. I always lean build.
