IT’S no stretch of the imagination to realise why Kayla Simmons has cracked it online.

Commonly called the world’s sexiest volleyball player, she revealed a warm-down routine that turned up the heat for her 1million Instagram fans.

One admirer described her bottom in figure-hugging gym gear as “outrageous”.

The influencer posted a short clip saying: “Making a habit to stretch after every outfit.”

Such manoeuvres are the big new thing in the gym.

And Kayla went out on a limb – or two – with some full-length body moves to show why her career is on an upward curve.

“Woah! Gorgeousss” said one fan of the American’s recent snaps, and “Cutee” raved another.

Kayla’s post-exercise routine comes hot on the heels of less serious horse-play.

She posed as a cowgirl for Independence Day celebrations.

Now she’s taken the ball by the horns to show her followers how to reduce niggling injuries after strenuous exercise.

It’s the latest twist(s) in the sizzling saga of her rise to the top.
