More than 75 pupils from St Mary’s Catholic College in Wallasey proved that exercise can be fun when they gathered for an aerobics class at a local leisure centre dressed in their “onesies”.

The young people were helping to promote the introduction of the “Teen Invigor8” memberships at Leasowe Recreation Centre and took part in an aerobics class dressed in their distinctive all-in-one outfits.

Increasing the numbers of young people regularly getting physical exercise is a priority for Wirral Council and local health authorities as, in their teen years, many kids who, when younger were bundles of energy, seem to lose interest in being active.

Between school, studying, friends, and maybe even a part-time job, there is a lot of competition for their time and attention.

Councillor Chris Meaden, Wirral’s cabinet member for health and wellbeing, said: “The NHS recommends that teenagers need an hour of physical activity every day to help stay healthy.

“Exercise can also help improve their mood and sharpen their mind.

“However, we know that fitting everything in to a busy schedule when you’re at that age is difficult, so with Teen Invigor8 we’re trying to find ways of making it easier and more enjoyable for young people to get the exercise they need.

“The ‘onesie’ exercise class proves how successful this different approach can be and I know many of those who took part will be back for more.”

Teen Invigor8 is aimed at 12 to 17 year olds in the hope of encoruaging them to become more physically active and involved in a wider range of healthy activities.

The membership includes access to Teen Fitness Suite sessions, teen specific exercise classes – onesies optional - and a range of other activities.
