Bowflex SelectTech 552 vs Oura Ring Gen 4
Verdict: These products serve fundamentally different purposes—one for resistance training and one for health tracking—so direct comparison is limited. Bowflex SelectTech 552 provides a space-saving strength solution with real 5-52.5 lb increments (per Bowflex specs) while Oura Ring Gen 4 delivers 7-day battery and continuous HRV tracking (per Oura documentation). Neither replaces the other; choose based on whether the goal is lifting or recovery monitoring.
Winner: Oura Ring Gen 4
Bowflex SelectTech 552: 7.5/10
Oura Ring Gen 4: 8/10
