Today I got almost a full hour workout in and it felt great. I did about 35 minutes of abs and strength training before I did 15 minutes of cardio just to round it out before I picked up my kids for the day.
I focused my strength training on my tri's, bi's and shoulders with some back exercises to balance it out.
I've had a real "hate" relationship with my arms for quite a long time now. No one to blame but myself- I let myself (and them) go- but I love seeing the changes and being able to see the muscles now. This coming summer might be the first time I'm willing to wear sleeveless shirts without serious problem.
I think I love the 100 Day challenge - it is keeping me very focused.
