I am working out 5 to 6 days a week. The staple of my workouts are burbees. I started at 5 per minute until I could get to 30 minutes and then started over with six per minute until I could hit 30 minutes. Right now I am at 9 per minute and died at 16 minutes. I will give it another shot tomorrow. Went on my first trail run this weekend, and just climbed 6500 feet in 12.3 miles last night and this morning. Only two and a half more months to torture myself. Hopefully it pays off.
