Dylan Alcott works up a sweat with celebrity trainer Jono Castano as he shares fiery gym video with fans

Dylan Alcott flaunted his bulging biceps on Tuesday as he took to the gym for a hard workout with celebrity trainer Jono Castano.

The three-time Paralympic gold medalist, 33, worked up a sweat in videos shared to Jono’s Instagram Stories.

In the first clip, the former Australian of the Year got his muscles burning with battle ropes before he moved onto pushups using press-up bars in the second. 

Jono, 33, kept close by Dylan, spotting him and giving encouragement as Dylan powered through his reps. 

In a show of mental fortitude, Dylan stuck his tongue out at the camera when his arms began to waver, before pushing through the struggle.

It comes just days after Dylan led the stars at the media call for The Rocky Horror Picture Show last Wednesday. 

The athlete took on the role of the narrator as he promoted the new season of the production which is playing at Sydney’s Theatre Royal from March 31 – April 17.

Comedian Peter Helliar will take over the role from the former wheelchair tennis star from April 18 through to the show’s closing on May 5.

Dylan announced his shocking career move in December last year, and said he was incredibly excited about his new acting role.

‘Super pumped to join this incredible production of the iconic show,’ he said in a statement at the time.

‘Couldn’t think of a better opportunity for my first theatre production, feeling very grateful. Can’t wait to get to work and rock it out on stage in Sydney!’

Dylan will be joined by a host of veteran performers, including Jason Donovan who will pick up the lead role of Frank N. Furter.

Other famous Australians who will take on the narrator role as the show tours are Myf Warhurst in Newcastle and Joel Creasey in Melbourne.

Dylan has previously expressed interest in branching out into acting.

In July last year, it was announced he would have a cameo in the upcoming season four of the Stan series Bump.
