I have been working out for about 20 years on a daily basis. While I sometimes miss a day I think I actually work out about 300 days a year. Started when I was in my mid 30s. Been in and out of sobriety during this time period. For me it's very beneficial. I realize that for most people exercise is really good for long term health. It's a lot more than helping me get or keep sober. I suggest you consider it a permanent habit.
