Bear Crawl builds strength and power, boosts your metabolism, and fires up your cardio fitness. This exercise uses almost every muscle in the body, including the shoulders (deltoids), chest and back, glutes, quadriceps, hamstrings, and core. Another great thing about bear crawls is that they provide a great mental challenge, as your brain focuses on maintaining balance while keeping all your limbs moving at once.

Challenge Description

The 14-Day Cardio Comeback is a focused, equipment-free plan designed to reignite your aerobic engine and rebuild stamina without overwhelming your joints. Across two weeks you’ll move from shorter work intervals to slightly longer efforts, rotating through athletic patterns like step-ups, lateral hops, crawling, jacks, and boxing combos. This blend keeps sessions engaging while improving heart-rate recovery, breathing efficiency, and total-body coordination. Expect to restore your baseline conditioning, elevate daily energy, and lay a durable aerobic foundation for future training. By the end of the challenge you should notice easier steady-state efforts, better resilience in stop‑start activities, and a stronger trunk and hips that support efficient, sustainable cardio.
