Day 4 of the gym this week!

5 minute warm up, elliptical
60 minutes strength training including those killer ab things!
30 minutes elliptical + 5 minutes cool down

Really rough cardio today....same resistance, pace, time....but I felt like giving up after 5 minutes! What the? It really bothered me...but I kept going (mainly because I didn't want to post on here that I could only complete 5 minutes....thanks guys for potentially judging me! That's what true friends are for!) ...but seriously...I could not figure out why I was having such a hard time....then I realized I only had a big Greek Salad for lunch...no protein! Well, some feta, but not enough to sustain me thru 90 minutes of workout! Dumb dumb dumb ....so, in the future, I promise to get in some more protein.

...anyone tried those protein shakes? Any reviews good or bad? I'm thinking if I have one of those on the way to the gym as I'm leaving work, it may help.

Please advise, anyone who has some experience with it....Thanks in advance!!
