What's your Fitness Textbook?

Tracking your progress and exercises is probably one of the most important things you should do if you want to achieve your desired results.
Three Reason Why:

1. By creating an exercise plan ahead of time you are ready to go when you get to the gym (unlike those people you see who get there and stand around dumbfounded trying to figure out what to do) 
2. By documenting and tracking exercise characteristics (type of exercise, weight used, reps, etc. you) you always know where you left off the last time you workout out and what your trying to improve.
3. Nothing Motivates Like Results! and results are much easier to see in numbers than in the mirror (but that will follow).

How:

• Pen and Paper - Sometimes simple is better.
• Online/App Tracking - I use Gym Technick  but there are hundreds of others in the app store.

One of the most versatile (and lightest) pieces of exercise equipment. With this system you can perform a nearly infinite number of different exercises, and due to its size its great for travel. (If the original TRX is out of your price range, there are tons of cheaper alternatives) 

Great way to get your heart pumping and De-stress. (plus you'll have a stronger punch in just a few weeks, and you never know when that will come in handy)
I got mine on Craigslist (in exchange for a old Sub-woofer)
Make Sure to Put it in a Highly Accessible & Visited Spot, such as a Living Room or Bedroom, Most People who buy Punching Bags Put them in Cold, Dark, Wet Places like Basements or Garages and are then surprised why no-one ever goes there to use it
