Adele looked so different at Drake's birthday party. The singer chose a look inspired by the 60s to best highlight the body after weakening.

Adele, who split from husband Simon Konecki in April, has stayed out of the public eye lately. But after Drake's holiday, she posted photos from the evening and, through the description, shared the new physical regimen with the world.

"I used to cry, but now I sweat," she wrote. According to The Sun, the secret of Adele's transformation is The Body Coach, Joe Wicks.

Wicks is known for his books "Lean in 15" and the 90-day plan designed by him to make you "stronger, more athletic, healthier and thinner." Adele seems to have used personal trainer videos to exercise in the privacy of her home.

The singer also worked with coach Dalton Wong, Jennifer Lawrence's favorite.

"Adele has worked in secret with these personal trainers," a source told the paper. "The progress achieved during these six months is more than obvious."

"She does not like exercising in the eyes of others, so she has followed regimes and plans at home, using videos and tutorials."

Joe Wicks recently moved to Los Angeles, where Adele also lives. So, it might have helped the singer personally.

The Body Coach plans consist of very intense exercises that last no more than 35 minutes. In addition to videos where he exercises, Wicks also posts simple recipes on Instagram that help his followers eat healthy.

If it did work for Adele, why not others who want to weaken.
