Can you absolutely and positively point out where your buttocks end and your upper thighs begin? If not, then you have what the fitness experts are calling - the 'thut'.
Thut, like muffin top and the stubborn flab under your arms, is the untoned meeting place of your upper thighs and bum, News.com.au reported.
People who work on their desk all day are the most likely to have a sag where there should be a pert little angle.
However, fitness expert Annie Mulgrew points out that your legs muscles, quads, hamstrings, calves and gluts can all be toned and in doing so you can absolutely create definition so that your butt appears lifted and firmed.
Mulgrew suggests rowing and doing squats to get rid of the thut. (ANI)
