Probably can find on CL if you wait long enough. This brings to mind a lot of things:
-A gym membership should be around $1/day and will likely yield a greater spectrum of yoga pants asses and a bit of a social scene. IIRC, for a newly single guy like you, that'd be my personal recommendation.
-If I were going to divvy up $2K to spend on equipment, I'd get a set of adjustable dumbells, a barbell with 225 lbs of weight, and a solid bench. I'd then look for a local trainer who emphasized that they cover both fitness and nutrition, and I would pay them once to come over and clean out your pantry & fridge, give you a list of good snacks/meals, then develop a full-body workout routine that you could do in conjunction with cardio. It takes 21 days to build a habit, so really the critical thing is getting into a rhythm with adding fitness/nutrition to your life.
--There's very few things that are as important as your mental/emotional/physical health. If a $2K machine makes you work out even 1 more time per week, that's totally worth it.
