Death by cross trainer...

OMG!!! Went to the gym (first time in months) did the following;
Cross Trainer - 10mins - level 15 - Completely knackered me out!! I was hyperventelating, I thought
                                                      my heart was coming out of my chest!! Hoping to get to 20mins!
Treadmill - 20mins - 5-5.5mph - Was breathing heavy but aiming for slightly faster time eventually, and....
                                                    maybe.....eventually.....jogging/running??
Bike - 20mins - 16.9mph - Level 2 - was ok, breathing ok and recovered quickly.

I felt good afterward tho so my goal this week is to make it to 20/20/20 of each and then I'll go from there!
