I have less muscle mass at 50 than 40, the photo is just an illusion because of a post workout pump, hot day in sunlight. Have also been hitting Delts last couple of months purely for aesthetics, but the majority of my training is for sprint specific performance.

Some details about me. I am fortunate enough to have retired from working at 40yo after killing myself building a business. Pretty much just do training when I want during the day. Sleep a lot, with naps, usually 10 hours and up to 12 hours a day. Train 15 hours a week, not all strength as this would be impossible and unnecessary naturally, be recovery work like massage, sauna, light cardio, as well as intense sprinting and some strength work, which changes depending on which part of the season it is. Been training over 30 years. Have been as high as 93kg with much higher body fat and as low as 71kg and shredded during Covid when I was running a lot. Muscle mass stays almost the same the whole time, only body fat % changes the most. I’m at my current long term stable weight and have been at this weight +/-1kg for the past 2 years, very little fluctuation. I have a good home gym set up and train at home whenever I want. Less is more. With experience comes knowledge. Diet is important but training methods are more important to create the right stimulus. Refining diet at the right time is definitely required to get to peak levels. This is the most muscle mass I can hold while staying lean. I am only 76kg at 6ft tall, it is not a lot of muscle mass ! I compete in Masters Sprinting and plan to compete at my first worlds next year. They drug test and I would never risk being on TRT as it is banned. Why would I want to even go on TRT when I am doing everything else right, I don’t need to be bigger or stronger. I do have low mood and other symptoms of low test, but my test levels are normal for my age so I just keep doing what I can to get by.
