To 'put your hands in the air' or 'hold your hands up' is an internationally recognised gesture meaning 'to surrender'. If you say you 'put your hands up' or 'hold your hands up' you are expressing that you have made a mistake or are accepting responsibility for something that has gone wrong. "I hold my hands up and accept that I didn't do as much as I could to get this project off the ground." This is an expression primarily used in the UK and you will hear it used in social and professional contexts in situations where people admit fault.
