Not exactly within budget but ~$400 gym membership (from Costco.. so, factor in the amortized cost of that, too, I guess) for 24 hr fitness for 2 years - going to the gym has been a HUGE game-changer for me. Never really did it before with any discipline, and already within 3 months there have been great dividends for me. I'm much stronger than I was just 3 months ago. Much less anxious and stuff too.
