Every training block follows a free consultation and induction. Sessions are booked directly with your trainer; 48 hours' notice to cancel. The extra sessions need the block paid in full, in one payment. There are 10 slots. A 20-session block can be paid in two payments instead, half before session 1 and half before session 11, at 20 sessions and the standard price. Everything else is paid up front. Sessions stay valid for two years from your first session. If you stop part way through a block within that time, the sessions you have had are charged at the standard single-session rate and the balance is refunded. After two years the block ends and no refund is due. Check availability before you buy.
