If running and rucking is your thing, then I highly recommend this
iFit enabled treadmill. We bought one last Christmas and have absolutely loved it.
My wife competes in triathlons and I've hiked and ran trails my entire life. If you've never used iFit, then you're missing out. Imagine pulling up an app that allows you to literally trace your route on your smart phone, tablet or pc and then transfer that route to your treadmill. It allows customizations to your resistance, elevation, etc to help you train for a specific route, which rocks whenever you're training for a 5k, half or full marathon.
Aside from that, we train in Krav Maga, BJJ and Kali/silat. So, our gym is atypical - kick shields, heavy bags, tombstone pads, ropes, rubber knives and guns, kettle bells, etc. BTW, your house looks awesome! You've done a great job and should be proud! Oh...and back to iFit...if you do have a smart phone, then download the free app and give it a whirl. Maybe you'll discover some added benefits to how it logs your activities and integrates into your overall cardio and fitness plans.
Best of luck!
