We don't just take your money, we donate it 80% of it to a charity of your choice. If you're going to be a lazy ass and pay a gym membership every month it might as be paid to a charity - right? right? Skin In The Gym is an accountability app live in Australia and Norway: commit to one to four sessions a month with $10 staked on each. Show up and pay $0. Skip, and $8 of that $10 goes to the charity you chose.
