"Grilling session at nca! Happy to hit a few balls after almost 6 mnths. Strength is ok need to build on cardio!! Target t20 w cup. Let's c," Yuvraj tweeted.
Yuvraj is in his second week of rehabilitation programme at the National Cricket Academy here.
"I am right now in the second week of rehabilitation and I am feeling good. My body will slowly become stronger, I am sure," he said while talking to reporters.
"The target is the T20 World Cup, and hopefully, I will be able to come just before that," reiterated the 30-year-old left-hander, who has not appeared in any form of the game since last November when he was diagnosed with the disease.
He underwent chemotherapy in the United States before returning to India in April to continue his rehabilitation.
Yuvraj again thanked one and all for the incredible support he received during his treatment.
"Great response... It is overwhelming... The wishes of the whole country. I want to come back and play for the country," he said here.
The 2011 World Cup's Man-of-the-Tournament had earlier said that "playing for India is going to be a huge challenge for me because the body has been under a lot of shock which nobody can understand except me".
Having already returned to light training, Yuvraj had also said that that his recovery was going well, and is enjoying a healthier lifestyle.
"I'm feeling good. It's been two months since I finished my chemotherapy. Initially my energy levels were low but now I am following my diet and eating loads of food and it's getting better," he had said.
