How far you can push yourself during a workout is becoming a test of strength, endurance, and stamina. From lifting heavier weights to spending longer hours at the gym, doing more can feel like a sign of progress. But as you embrace a relentless approach with your workouts , are you giving your body enough time to recover? And to what extent can you push until your heart starts to feel the stress ?
The cardiologist revealed no. Answering these questions about exercise intensity and heart health, Dr Manish Aggarwal, director of interventional cardiology and structural heart at Yashoda Medicity, shared with HT Lifestyle that you should closely monitor yourself when pushing yourself during a workout. Health and wellness culture can encourage people to stay active, but sometimes the focus shifts towards extreme fitness, where pushing harder and training longer become measures of success. How can this affect your heart? The cardiologist highlighted activities such as marathon training, HIIT (high-intensity interval training,) long-distance cycling, boot camps, and gym workouts, explaining that concerns arise when people increase the intensity too quickly or do not allow enough time for recovery. Exercise itself is not the problem, as regular physical activity helps reduce the risk of heart disease. So, when does it become a concern? The cardiologist cautioned that the problems can arise when people push their bodies too hard, too quickly. He described heart, muscles, and joints need time to adapt and adjust, especially when someone moves from occasional exercise to a demanding training routine. Does this mean endurance sports are bad for your heart? Some endurance athletes have been found to have conditions such as atrial fibrillation or increased calcium deposits in their coronary arteries after years of vigorous training. However, this association does not establish that vigorous exercise directly caused these changes. Now, does it mean endurance sports are bad? How much exercise should you aim for each week? The cardiologist outlined weekly activity targets, emphasising that your workout routine should suit your fitness level and allow enough time for recovery. Those who are already active can gradually increase their volume, but intensity should still be matched to their fitness, age, health conditions and recovery capacity. The cardiologist listed these signs that may signal a need to reduce your exercise load: He also emphasised the importance of proper hydration, nutrition, sleep and recovery days, especially as training intensity increases. During a training session, people may dismiss weakness or discomfort as a sign of being ‘out of shape. But, some symptoms should not be normalised, as they may indicate a medical problem that needs prompt attention. Dr Aggarwal shared these signs during exercise which mean you need prompt medical help:
Dr Aggarwal said, “For most adults, a practical starting point is at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week, along with muscle-strengthening exercises on at least two days. But the intensity matters as some endurance athletes have been found to suffer from problems such as atrial fibrillation or increased calcium deposits in their coronary arteries due to their years of vigorous training, but that does not establish a direct cause.
“Vigorous exercise can raise the risk of heart disease among people who have never trained before,” Dr Aggarwal said, highlighting the importance of gradually building up exercise intensity. The cardiologist said no, but emphasised that exercise intensity matters.

Individuals suffering from cardiovascular diseases, hypertension, diabetes, past heart issues, or those who have a family history of sudden heart attack should consult their health care providers before undertaking a strenuous exercise program, according to the expert.
