I’ve been doing a kickboxing class these last few weeks, and have enjoyed it. It’s been £5 a session up til now, but now they want me to sign up with a direct debit of £24 a month, and also pay a £50 license/insurance fee, and buy a ‘uniform’. This seems like a lot of expense for 1 hours training a week. Is this normal?
Also, I think 1 hour a week isn’t enough, do kickboxing training gyms exist with punch bags etc, and how much do they charge?
£6 is equivalent to about $12 by the way.
