Pittsburgh hills killing my legs

My legs are busted from all this uphill biking. I've been going up and down (to SqHill, Shadyside, Greenfield, etc) about 4 times a day. I should probably give them a day of rest tomorrow. I guess that means I'll have to bike with my hands, or maybe, just maybe, take the dreaded bus.

My legs are much stronger than my arms already. This new lifestyle will probably only contribute to the imbalance.

my Pittsburgh

if I end up living on Elysian St, that is.

It's a nice apartment. $600/month + utilities for an unfurnished (except for 2 ACs, dishwasher, stove) 3rd floor (roof) aparment: 15m^2 bedroom, 15m^2 living room (which can easily become a second bedroom), spacious kitchen, 1 bathroom, and some space in the stairs. The main problem is that I don't know of any supermarkets around, and maybe it's a little bit far.

Can anyone tell me about important supermarkets in this map, besides the G-Eagle on Murray?
