Garage Gyms

Now that we're moving into a bigger house with a garage, my husband and I finally have the opportunity to build an "at home" gym. Because I have a strong foundation in Crossfit, instead of getting the typical Bowflex and Gazelle fitness equipment. I have the opportunity to build a true garage gym - although it still probably isn't going to look like a typical box, simply because it's expensive and I don't have time for that. Here are some essentials that I will need for my new gym -
Kettle Bells

You can use kettle bells in so many ways. A lot of crossfit workouts use them in the "Workout of the Day" such as
Helen:3 Rounds For Time
Run 400m
21 Kettle Bell Swings 55lb
12 Pull Ups

I'm probably going to get the 1 pood, which is 32 lbs and then as I get back into it, I can get the 1 1/2 pood which is 53 lbs. You can also use kettle bells for workouts such as kettle bells snatch, kettle bell cleans, etc etc. Even Bob uses them on the Biggest Loser
Medicine Balls
but not the little rubber ones. I don't like those as much. I'll get these -

They're good for wall balls and actually, I use them to squat too. It helps me know where to touch my butt and make sure I'm breaking that 90 degree plain. If you're not squatting below where your knees break the plain, you're not squatting. And I like to cheat since I have long legs so... yeah...

Self explanatory. I'll probably get 12 lbs and 20 lbs. My hubby will probably want bigger ones for him. 
Pull Up BarWe're going to have to make one. I don't know how yet. I'll need a stable one, not those ones that are portable. 
That's where i'll start. What I would eventually like to add is - 
Olympic Bars/Bumper Plates (rubber)

Boxes for Box Jumps

I only need one and it needs to be 20"

If I can get some of this stuff after we move, I am thinking I might try Crossfit Endurance to train for my next half marathon. Basically, you do your "sport" (run) 3 days a week using the endurance training plans for the day, and also do the Crossfit strength & conditioning workout for the day that has been developed for endurance athletes. We'll just see how it goes. 
Do you have a home gym?
