Marla has been regularly meeting her friend to run three mornings each week. They run for the same amount of time along the same stretch of road. They maintain consistent, easy conversation throughout each run. Marla and her friend are increasing their physical fitness.

As they continue to run together, Marla and her friend notice a significant improvement in their endurance and overall physical fitness. They are able to run longer distances without feeling as tired and are also able to maintain a faster pace. Their regular runs have also had a positive impact on their mental health, as running together gives them a chance to catch up, talk about their day, and provide each other with support and encouragement.

Overall, Marla and her friend's regular running routine has not only helped them improve their physical fitness but has also strengthened their friendship and provided them with a fun and healthy activity to do together. They look forward to each run and are excited to see how much progress they can continue to make in the future.
