The 24-year-old collapsed after suffering a cardiac arrest in the FA Cup clash at Tottenham Hotspur and was 'effectively dead' for 78 minutes.
Since then Muamba has made a miraculous recovery and amazingly left hospital after just over a month of treatment.
Reliving his first steps, Muamba told The Sun: "Once I was on my feet for the first time I felt like a toddler again - like my three-year-old son Joshua. I could barely put one foot in front of the other and had to be carried back to my bed - but it was a start."
The midfielder has been building his fitness by taking short walks with his fiancee Shauna Magunday.
"A few months ago I would think nothing of running miles, but now I'm tired after a 20-minute walk around the block," he said.
"But now I'm making progress. It's too early to say whether I'll play football professionally again but I have great faith in God and I have hope, so who knows? If I can come back from the dead then perhaps I can achieve anything."
