In this YouTube segment, fitness coach Rodrigo Barros points out the most common mistake people make on stair‑climber or cardio stair machines: leaning heavily on the handrails. He explains that this habit unloads the legs, turning a powerful lower‑body workout—essentially a split‑squat movement—into a ineffective exercise that fails to engage the glutes and quadriceps. Barros notes typical gender‑based patterns, such as men often using their phones while exercising and women exploiting greater elbow flexibility to rest on the rails. He also highlights another error: using a resistance that is too low, which prevents the cardio machine from delivering the intended cardiovascular stimulus. The coach stresses that cardio must be performed at an intensity that leaves the practitioner breathless; only then does it produce meaningful results. Throughout, he uses a conversational, instructional tone, demonstrating the correct posture and urging viewers to eliminate these habits for better fitness outcomes.
