Ronaldo boasts outrageous leg muscles as Real Madrid stars pose for group photo

After a season which has featured plenty of disharmony and criticism, Real Madrid are currently flying high and in good spirits.

Los Blancos take on Athletic Bilbao at the Bernabeu on Wednesday before the first leg of their Champions League semi-final duel with Bayern Munich.

And any suggestions that Cristiano Ronaldo is running on empty after another stunning campaign appear well wide of the mark as he boasted his outrageous leg muscles after training on Monday.

Zinedine Zidane's starman showed off his shredded physique as he pulled a bizarre stern face with team-mates happy to joke around following the conclusion of Monday's session.

Kiko Castilla, Toni Kroos, Borja Mayoral and Raphael Varane were among the team-mates happy to join Ronaldo and his muscles in the snap, captioned simply by Varane as '#HalaMadrid'.

With 42 goals from 42 appearances - 15 in the Champions League already - Ronaldo is showing the fruits of his meticulous preparation and desire to keep himself in the best possible shape.

His kicking power is helped immensely by his bulging quadriceps but muscle retention is something the 33-year-old has worked hard to build-up and sustain throughout his career.

He swims at home after games, alone or with his son Cristiano Jnr.

After swimming there is more water therapy with hot and cold baths to stimulate muscle regeneration, a high-pressured water jet to massage muscles, and a walk-in cryotherapy chamber.

He had a chamber installed in 2013 after hearing it had worked well for Bayern Munich’s Franck Ribery.

The liquid nitrogen treatment reaches temperatures between -160°C and -200°C — bearable for about three minutes but with huge regenerative dividends.
