Tammy was promoting her TammyFit app in the caption, which includes focused booty workouts.

During an appearance on Studio 10 in 2019, Tammy described the strenuous workout regimen that helps her achieve her famous derrière.

‘I do a lot of heavy weights. You’re not going to build any muscle if you are not doing leg weights. I see a lot of girls doing cardio and this and that, it is not going to build any muscle really,’ she said.

When asked how heavy she goes with her weighted squats, the blonde shocked the panel by saying she could easily perform 60kg.

Tammy also told the hosts she ‘hates’ it when people falsely accuse her of having undergone a Brazilian butt lift.

‘I hate when people accuse me of doing that… I take such offence to it because I worked so hard and it makes me annoyed.’
