My workout today was elliptical changing difficulty levels every minute. Level 15; 16; 17; 16; 15; 16; 17; 16; 15 until my 60 minutes of fun were up. It makes really cool oscillations in the recording of my heart rate.
I'll be training a group from work to run a Spartan race in August; 8-10 miles and ~25 obstacles. It should be interesting because some of them are below average in their current level of fitness. I'll have to gut it out until my shoulder heals completely but I'm looking forward to the race.
