Running and laughing

Today for my lunch time workout I completed 20 minutes and just about 3 miles on the (more challenging) elliptical, level 3 resistance. Then I completed this little circuit twice:

• 20 standing side crunches with 15 lb. weight  
• 12 bicep curls seated on ball with 6 lb. weight
• 20 crunches on the ball
• 12 front chest flies on the ball with 6 lb. weight
• 20 squats with 6 lb. medicine ball
• 20 Russian twists with 6 lb. medicine ball

I finished up with a little bit of stretching and rushed back to work.
