Objective: Bodyweight interval training (BW-IT) using a social media platform may appeal to those who do not wish to exercise in public or do not have access to specialized exercise equipment. We investigated the ability of a 6-week BW-IT program to improve cardiovascular and metabolic markers. Methods: Fourteen adults (30.7 ± 10.3 yrs.) with obesity (body mass index 35.5 ± 5.4 kg/m2) participated. Bi-weekly program progression was applied by increasing the duration of the work intervals to 60s with 60s active recovery. Peak oxygen consumption (V̇O2peak), isometric muscular strength, body composition, blood pressure (BP), and metabolic blood markers were assessed pre-and post-intervention. Self-efficacy, constructs of the Theory of Planned Behavior (TPB), and physical activity enjoyment (PACES) to BW-IT were also assessed. Results: An increase in muscular strength ~10% (+ 0.2 ± 0.2 Nm/kg, P = 0.02) and V̇O2peak ~5% (+ 0.1 ± 0.2 L/min, P = 0.02) occurred. Waist circumference (WC) and waist-to-height ratio (WHtR) reduced (WC -2.2 cm, P = 0.03, WHtR -0.01, P = 0.02). Self-efficacy in allocating time to schedule BW-IT reduced upon program completion (-13%, P < 0.05). Conclusion: Bodyweight interval training elicited slight improvements in muscular strength, surrogate measures of abdominal adiposity, and cardiorespiratory fitness in adults with obesity.
