Have you ever wondered why someone who lifts weights regularly avoids cardio exercises like running or climbing the stairs? Dr Sarang Deshpande is a consultant in orthopaedics at KIMS Hospitals in Thane. He said that this scenario could indicate if the body is strong for certain movements but weaker in everyday activities. “Lifting increases muscle fibres, but does not help the heart or lungs. Simple tasks such as climbing stairs, running for a cab or carrying shopping bags a long distance can cause fatigue. The heart isn’t trained to pump efficiently, so even mild effort can push it into overdrive faster than expected,” said Dr Deshpande.DISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to.

Strength training increases power, but not oxygen capacity. “Without cardio the blood flow to muscles is limited, which slows down recovery and increases soreness. Can skipping cardio also affect joints? Yes, but indirectly. Dr Deshpande. Poor endurance can alter posture and movement patterns. When the body becomes fatigued quickly, the form deteriorates more rapidly, which puts stress on the knees and hips. Running is a great way to stay active. It improves circulation, flexibility and mobility. (Photo: Pixabay). Does avoiding cardio slow down fat loss? It often does, according to Dr Deshpande. “Cardio speeds metabolism and helps your body use energy more effectively. It is essential for fat loss to be accelerated, otherwise you will end up with a bulky look without definition. ‘This time, not 85 but 86’: Helen demonstrates simple exercises to improve mobilityWhat to note?Dr Deshpande shared that a mix of strength training and basic cardio, such as brisk walking, cycling, or light jogging, improves body function.
