But I've known this about myself for years, so I have slowly been accumulating a home gym.
The most recent addition to my home gym is this weight bench, the back of which adjusts to different degrees for different exercises. You can barely see it, but there's a pull-up bar, the kind you put in a door frame, underneath the bench.
The floor is flat enough to set up my bike and trainer, which I use to warm up before lifting, or as a full cardio work out post-strength training.
My array of free weights and gloves. The newer set of weights I bought a few years ago. The older set belonged to my grandfather, who gave it to my mom, who recently gifted it to me.
Stereo to play workout music to keep me motivated! Also pictured are my collection of exercise bands (great for shoulder and other joint stability exercises) and Hot Bod in a Box: a collection of strength-training exercises compiled by Jillian Michaels.
This exercise mat is amazing. It comes in puzzle pieces, so you can add or subtract from it to make it the size and shape you desire. In the center of the mat is my stability disc, which I got mostly to strengthen my ankles for trail running, but it provides a pretty difficult abdominal workout, too. The full-length mirror helps me keep my posture in check during activities. (I found the mirror under the basement stairs when I moved it!) There's also a medium-sized stability ball that I use for abs and lower back. (Bonus: you may also notice the random Beatles poster to the left; no home gym is complete without one :-P )
And who is this? She's my personal trainer! Can't you just hear her yelling "Just one more! Push it!"
Not pictured: my yoga mat, bands, and blocks. I keep them in the living room where I watch yoga DVDs.
