Legs, Bums & Tums (LBT)

Legs, Bums & Tums (LBT) is an aerobics lesson that focuses on stimulating the burning of fat and strengthening the Legs, Bums & Tums. In this ticket hour we combine cardio- and strength training. Strong abdominal and gluteal muscles reduce the strain on your back. Strong leg muscles will allow you to get to the lecture hall faster. You will progress and feel stronger and fitter.

Ticket hour - All levels

This 45-minute BBB workout targets strengthening your abs, glutes, and legs through a series of focused strength exercises.

You’ll use weights, barbells, and resistance bands (elastic bands) worn around, for example, your legs to add extra resistance. By incorporating this resistance, you challenge your muscles more effectively, helping to build strength and endurance.

The workout is approachable and suitable for anyone looking to improve strength in their core, glutes, and legs in a targeted and accessible way.
