There are endless options for fitness in Bucharest, but here are just a few starters
- www.fitpass.ro (my personal favourite subscription)
My personal views: Having recently just joined Fitpass myself, a subscription that costs as little as 20 euros per month for twice-weekly gym access, I thought it helpful to share the great range of activities available. See diagram below & use this discount code to receive 10% off your subscription. To my mind, this is by far, the best value for money gym/ activity membership money can but at this time in Bucharest or Brasov.
