Nico Rosberg sets his sights high for the Malaysian Grand Prix.
CNN  — 

Lewis Hamilton may be on top of the world but his Mercedes teammate Nico Rosberg reached new heights during his unusual preparations for Sunday’s Malaysian Grand Prix.

The 29-year-old ran to the top of the famous Petronas Towers in downtown Kuala Lumpur as part of his training regime for the grueling race on Sepang’s sizzling circuit.

A sweaty and gasping Rosberg was filmed jogging up the staircase in an agonizing 19-minute climb to the top of the 1482 ft building.

He then tweeted “great training session up one of the Petronas twin towers in KL. 2170 steps!! They are high!”

Once the German reached the top he took a breather whilst taking in the stunning views of the Malaysian capital.

Petronas Motorsports tweeted the film of the Mercedes driver with the caption “Tower 1 of the PETRONAS Twin Towers becomes @nico_rosberg’s gym for the day. 2170 steps, up 84 floors in 19 minutes.”

The Malaysian Grand Prix is one of the most physically demanding because of the hot and humid conditions. The drivers can sweat out up to three liters of fluids during the race.

Rosberg’s unique training session may help give him the edge as he prepares to renew his on-track rivalry with world champion Hamilton on Sunday.

The Briton beat his Mercedes teammate by 1.3 seconds to win the season-opening Australian Grand Prix.
