Hiring a personal trainer and work out 5 times a week (only 2 with a trainer though, soon 1).

YMMV, a trainer has allowed me to fix goals and get tailored exercises so I progress quickly.

I repeat the exercises I did with the trainers the other days of the week.

Since I am not a morning person, I go to the gym in the evening, so I often go there , have a shower and go to sleep.

It has tremendously improved both my sleep and my energy levels.
