Two heterosexual runners, Adrian Hart and Jesse Stone, receive instructions from their trainer to engage in yoga for the upcoming season. Despite feeling skeptical, they comply, sporting snug yoga attire. While following a workout video showcasing attractive females, the friends become sexually excited, unable to conceal their arousal due to their tight outfits.
Understanding their inability to focus on the exercise routine, they fabricate alibis to masturbate next to each other. However, this solitary act proves insufficient, leading them to engage in a comprehensive physical training session together.
