Many women could be wasting their time performing endless squats, says Alesha Dixon’s personal trainer Janet Malinowska, because they’re not working your gluteal muscles properly – and could be causing harm to your back.

‘Many women have trouble performing normal squats and this is due to the Q angle position of the female pelvis (associated with our wider pelvises), and also tightness in the ankles from wearing high heeled shoes,’ she explains. ‘Women tend to lean forward a lot when squatting, rather than squatting down and backwards (as if sitting back in a chair) because of the issues above, which means they can overload and place pressure on the back (see image below).’
