Every week, a new STACK Challenge gives you an opportunity to test your athletic ability and win a STACK T-shirt. Take the challenge and enter to win by tweeting your results with #STACKChallenge.
Training for speed and conditioning this summer? Take the 300-Yard Shuttle test today, then twice more this summer to track your progress. It’s the same test Chicago Bears coach Marc Trestman famously implemented last summer when his team reported to training camp.
To complete the challenge, place two cones 25 yards apart. Sprint back and forth between the cones, making sure you touch each one. Repeat for 12 lengths for a total of six round trips.
Complete the 300-Yard Shuttle as fast as possible.
How Do You STACK Up?
