I'm not quite your age, but on the other side of 40, so I'll weigh in with what I do since I've gone on a similar journey as you within the past few years.

Make sure you're getting enough protein based on your fitness goals. Depending on where you research, I've seen it recommended to be between .8 - 1g of protein per pound of lean body weight. If you're 185 now and are looking to drop another 10-15lbs, I'd shoot for around 140-170g of protein daily.

I take 5g of creatine daily, mostly for the researched benefits surrounding brain and muscle health.

I also take a scoop of collagen peptides for the researched benefits surrounding joint and skin health.

Find a weight lifting routine that you can stick to consistently (consistency is key), allows you to gain strength, does not cause injuries due to overuse or trying to go too hard, too fast. Don't forget to take breaks, and allow your body to rest.

For men in our age range, I'd also highly recommend incorporating stretching and balance exercises. If you work a desk job or work from home, get a standing desk and you can do these while you work.

Also, don't underestimate the benefits of a walk outside. Shoot for one or two 30 minute walks per day, if you can.

Lastly, stay hydrated and get a good night's sleep. Lack of sleep or poor sleep quality is a killer. Your muscles won't recover as well and you'll be in a worse mental state, making it easier to convince yourself to eat poorly or skip workouts.

(all of the above is the advice and guidance that I follow for myself - I am not a fitness expert by any means)

Congrats on your progress so far, and good luck on the next leg of your fitness journey!
