You'll be working out five times a week, and you will get seriously hot and sweaty (especially if, like me, you end up on cycle three during a heatwave), so make sure you have plenty of stuff to wear while working out. Those with boobs will require a good quality, supportive sports bra as the workouts include a lot of jumping. If you're D+, I wholly recommend the wired one from Panache (£42) or the Shock Absorber Support Bra (£37). You'll also need a good pair of well-fitting trainers with good grip.
