While different items will make an appearance in my bag now and then, these are the tried and true standbys. It looks like a lot more now that I have them all listed out; I promise it's not all that heavy!!
My Bag -- Adidas Women's Ultimate Club Bag
A lightweight but sturdy gym bag that's held up to a lot of travel. Tons of pockets inside and out (including a tablet sleeve, a key fob, and multiple small pockets, including one just for a smartphone). I can fit everything I need and more in it. And, it's specially made for sports and the gym, with ventilated "FreshPAK" compartments. Check out more details here.
Side Pocket -- Fuel:
My preference is always to try to eat at home before a workout or run and come right home after, but sometimes it just doesn't work out that way, especially when I am on the road for work. Knowing this, I usually keep a Picky Bar in my bag for a preworkout snack and an EAS Advantage CarbControl Shake that I can pour over ice if it's been a harder workout and I won't be eating a real meal soon after.
If I am in dire need of some quick pre-workout energy, I'll grab the peanut butter GU in my bag. I discovered this flavor in my Stridebox and like it a lot. While I usually just save these for mid-fueling on long runs/races, they are so small that it's really no biggie to just keep one on hand, just in case.
Water bottle, nothing special
Altoids (Peppermint) or gum
Main Pocket -- Gear:
Tifosi Tyrant Wrap Sunglasses -- good sport sunglasses; not the most stylish shades but they don't fog up in heat/cold and the sturdy rubber part that sits on your nose keeps them from sliding around, even when sweaty!
Yurbuds -- I have ridiculous "mini ears" per the Hubs, so these in-ear buds are working for me.
Tuneband for iPhone 5 -- for my money, Tuneband makes the best fitness armband for phones/ipods/mp3 players, and I've tried a lot of other ones. the Tuneband models for previous iPhones are equally good.
Usually some form of a hat or sun visor if I am going to be outside, I have trouble with sweat/headbands staying put, and I like to keep the sun directly off my face if I can. Nike makes some good visors for women in their Dri-Fit fabric; I have a couple similar to this style that I have picked up at various places when I've seen a good sale.
Smaller Toiletry Bag -- Personal Care
Basics: Pack of Tissues, Deodorant, Toothbrush, Toothpaste, Small Hairbrush and Extra Ponytail Holders. I am not picky about any of these, frankly, and generally buy whatever is on sale and spend my money on other items below.
A pack of Neutrogena Oil-Free Pink Grapefruit Cleansing Wipes or Neutrogena Hydrating Wipes, usually whatever was on a better sale at the time I went shopping for new ones (right now it's grapefruit) and Johnson and Johnson Baby Wipes for random clean-ups. I really don't know how I get so messy during a workout, but I find a way.
Some form of anti-chafe for inner thigh madness (I have never in my life been known to have any semblance of a thigh gap); currently using a stick of RunGuard Anti-Chafe I received in my Stridebox, but I am not all that picky between this and Body Glide.
Chamois Butt'r for riding my bike; it's pretty much the same thing as the two products above (anti-chafe) for cyclists, but more lotion-y.
In Case of Emergency -- For Post-Workout Quick Presentability:
While I would love to think that my schedule will always work out to allow me time to go home and pull myself together, that is sadly not the case. I have found that there are a few miracle products with which, when kept on hand, I am able to pull myself together to a reasonable degree, even after a workout.
Oribe Texturizing Spray (really acts like a dry shampoo to absorb oil at roots, don't let fancy name confuse you)
Shiseido Blotting Papers (there are other good brands; Japanese brands tend to be best though and are my pick for oily, post-workout skin)
