Coming out of my Food and Exercise Ruts

As I have mentioned before, I am in a major food rut now. I am even not loving oatmeal which is usually my favorite meal of the day. It might have something to do with how hot it's been- steaming oatmeal just doesn't have the same appeal. So today I woke up and had an english muffin with almond butter and some sliced apple. I thought I'd be starving by snack time (yes, I still eat like a five year old even in the summer) but I was not much more hungry than usual :) Then, after work today I did a little Trader Joe's trip in hopes of getting something delicious for dinner. I'd say I was pretty successful!
I got "rice sticks"- which is basically rice pasta, zucchini, chicken and a sauce I had never tried before called Island Soyaki. I cooked the chicken out on the grill and then sauteed it in the sauce. The rice sticks were cooked exactly like pasta, but a bit quicker. I mixed it all together in one of my favorite bowls. It didn't look so pretty, but the new sauce made it taste completely different than my usual food, just what I was looking for!
I highly recommend that Island Soyaki sauce for those of you that are fortunate enough to have a Trader Joe's near you.

I also hoped on my bike for the first time since the triathlon today. I have been having trouble motivating myself to do much of anything since the triathlon but I know I need to get back into it. I did some invitations for one of my friend's shower so I decided to bike to the mailbox about 2.5 miles away to send them out. I know a 5 mile bike ride is nothing to write home about, but I really want to get back in a biking routine because I'd really like to do a 30 mile bike ride through Boston at the end of September. I also have to decide I want to keep my gym membership. I joined the YMCA near my house in May because I needed a pool to train in. I did a student summer membership, so my membership is up very soon. I think for now I probably will not renew, but I am thinking if I still can't run in the winter, walking on the treadmill is not going to cut it every day! I wish gym memberships would just be cheaper.

Also on the note of exercise, I am trying to work on arm toning. However, I have never had a good routine for arms with free weights. The best I ever did with my arms was when I was doing Jillian's 30 day shred. However, Jillian loves squats and jumping- neither of which are good for my knee- so unless I want to spend 20 minutes doing only half of the actual work out, the shred is out for me right now. Does anyone have a good arm routine? I'd love to do 10-15 minutes 3-4 times a week. Any ideas would be appreciated.
