Quality sessions of high intensity training looked to have benefited Lee Zii Jia, who trained with the likes of Loh Kean Yew and Rasmus Gemke ahead of the Denmark Open, which begins on Tuesday.

Lee had arrived in Denmark last week and was scheduled to train with Viktor Axelsen and Anders Antonsen.

But with Axelsen’s participation still in doubt after a leg injury, Lee trained with Loh and Gemke and was pleased with his run-up to the Super 750 event.

“It’s good to have high intensity training before a tournament. Here is all about intensity and quality of training,” Lee, who trained under the watchful eye of Danish singles chief Kenneth Jonassen, told Danish broadcaster TV 2.

The world number three aims to get his career back on track after crashing out early in his last three tournaments at the Malaysia Open, World Championships and Japan Open.

Lee opens his men’s singles first round account against Dutchman Mark Caljouw.

In the men’s doubles, Aaron Chia-Soh Wooi Yik play their first match as new world champions when the fourth seeds take on German pair Mark Lamsfuss-Marvin Seidel.

Goh Sze Fei-Nur Izzuddin take on Lee Yang-Lu Chen, while eighth seeds Ong Yew Sin-Teo Ee Yi are up against Liang Wei Keng-Wang Chang.

Tan Kian Meng-Tan Wee Kiong, meanwhile, see action against South Korea’s Choi Sol-gyu-Kim Won-ho.
