Walmart offers the CAP Barbell Doorway Sit Up Bar, model no. HHC-CB1, for $5. Opt for in-store pickup to avoid the $5.97 shipping charge. That's tied with our mention from a week ago and the lowest price we could find by $2. It features steel construction and padded leg rests.
Of note, your purchase at Walmart also includes a 30-day trial of Daily Burn streaming workouts.
