Two days MC

I am on two days MC, as doctor said that I have torn part of muscle fibre on my triceps, after I have overworked them on Sunday in Orchard Ngee Ann's City California Fitness.

So basically, I have spent most of the day on bed, trying to get as much rest as possible. 

On top of that, I have taken my very first protein drink in my life today. A chocolate flavour protein shake which I bought from GNC in Ang Mo Kio hub.The reason why I had protein drink, although is utterly dear,  is to hope that I could recover quicker. 

I am wondering what should I do tomorrow if I am doing quite well. :)
