Women's running wear label Thoosa has launched its second collection consisting of the Swift, City and Chill ranges for instructors who want to add a touch of glamour to the workplace.

Comprising last year's best-sellers in vibrant new colours, the tops and bottoms are flattering in shape and are made from light, breathable fabrics.

The Swift range offers the essential core items for any runner, with a long racer-back vest designed to fit over sports bras.

Thoosa's City range is longer and looser, designed with ultimate comfort in mind, and includes best-sellers from the debut range including the City vest (pictured).

Finally, the Chill range is intended for the colder months of the year with its technically-advanced fabric made with bamboo charcoal.

Items include the Chill hoody, which features mitten cuffs to keep wearers' hands warm - perfect for outdoor personal training sessions.
