Yes (kind of Our amazing Pilates teacher has just left Edinburgh so we’re high’n’dry without a comparable replacement).
However, if you go to a proper class you will sweat, you will feel like you’re exercising both at the time and the day afterwards and you will feel the difference in core strength.
IMHO books and DVDs cannot ever replace a decent teacher – look up private classes in your area and give it a try. You won’t look back…
I’m genuinely gutted our teacher left, no where else does the same level – its all leisure centre classes for al levels, rather than the bespoke personal experience.
