HIIT is a form of cardiovascular exercise. These short, intense workouts provide improved athletic capacity and condition, improved glucose metabolism, and improved fat burning. Exercises, 60 seconds each: - High knees - Jumping jacks - Squats - Leg raises - Lunges - Plank arm raises - Plank leg raises - Planks with rotation - Climbers - Push-ups Benefits: - Aerobic benefits - Metabolic benefits - Cardiovascular disease - Apple HealthKit integration : post your workouts on Apple Health automatically, by enabling Apple Health integration from the Settings Panel (by default it is disabled) 6 REASONS to start training: 1. Build yourself a smashing fit body - because there is no greater feeling than looking in the mirror and simply just love what you see. 2. Brag around about your toned muscles - low body fat level, noticeable muscle definition and shape, but not significant muscle size 3.

Verdict

The call

The clearest difference is ads: HIIT Workouts Challenge at none against HIIT's shown. HIIT Workouts Challenge also leads on monetization model (free vs freemium) and review sentiment (100% vs 91%). HIIT's advantage is ratings volume (31K vs 1) and update cadence (monthly vs every 2 months). On price, rating, in-app purchases and device support there is nothing between them.
