The renovation includes an investment in state-of-the-art equipment from fitness company Technogym.

This is due to a five-year partnership between the business and the University of Edinburgh.

"It's a real honour for us to have reopened the refurbished gym in Eric's name," said Mark Munro, director of sport and active health at the University of Edinburgh.

"Our partnership with Technogym has enabled us to create an amazing space which I am sure will help inspire our whole community to stay active."

The 765 square-metre space was previously split into two areas - one for cardio workouts ands one for fixed weights activities.

These have now been brought together to better serve the facility's users.

For cardio, there are now 30 new treadmills, 15 cross-trainers, nine exercise bikes, and for the first time, eight stair climbers.

There has also been an increase in the number of pin-select strength equipment including additional leg press, leg extension, lat pull, and low row machines, as well as the introduction of two hip thrust machines.

In total there are now over 130 pieces of elite-level equipment in the space.

Liddell enrolled at the University in 1920 to study pure science and was active in athletics and rugby union there.

His best event was the 100 metres, which he was due to compete in at Paris 1924.

However, being a devout Christian, he withdrew because the heats were going to be held on a Sunday.

The schedule had been published several months prior and so Liddell trained for the 400m in which he eventually won gold against the odds in the French capital.

His story is chronicled in the 1981 film Chariots of Fire which won four Academy Awards, including Best Picture. 

The gym renovation marks the launch of the University of Edinburgh's Eric Liddell 100 campaign.

The initiative comprises a series of events and activities aimed at celebrating the life of Liddell.
