Home Gym

Hello everyone! I'm in the process of creating a home gym. We are buying things one at a time to lessen the cost. We currently have a pro-form hybrid trainer (turns into an elliptical and bike) and have a treadmill ordered. We also have an old workout bench and some free weights. I have some resistance bands and yoga supplies as well. Once we have more space (my home office is currently in our gym area) I plan to buy a mini trampoline because they just look fun! Can anyone think of other things we could look into adding that won't take up much more space? We like to have a variety to our workouts so that they don't get boring.
