Most of my workouts came from the MTN tough program. I added sand bags when I started to plateau with my progress. I try to run as often as I can. I went too hard last month and I'm pretty sure I have micro fracturs in my tibia from trying to up my mileage too fast. So my workouts have changed to rowing and biking for cardio. Squats and lunges. Low impact everything for the next month or so. I've been hiking a local hill more often, and I've notice a huge difference getting up and down. Some days with 35lbs some days without. Just whatever my legs are feeling when I wake up.
