Heavy impact on knees and ankles
💡 Better alternative:
- Regular squats
- Slow controlled squats with proper form
- Low-impact step-ups
🧎 3. Full Sit-Ups (Traditional Crunch Style)
Full sit-ups are often used for core training, but they can strain the spine if overdone.
⚠️ Why to be careful:
- Puts pressure on lower back
- Engages hip flexors more than abs
- Can cause discomfort for beginners
💡 Better alternative:
- Planks
- Dead bugs
- Crunches with controlled movement
🦵 4. Deep Heavy Leg Extensions (Machine-Based)
Leg extension machines isolate the quadriceps, but heavy loading can stress the knee joint.
⚠️ Risks:
- Knee joint pressure at full extension
- Potential strain with heavy weights
- Not ideal for people with knee sensitivity
💡 Better alternative:
- Bodyweight squats
- Lunges
- Step-ups
🤸 5. Excessive Burpees (Without Proper Conditioning)
Burpees are a full-body exercise, but they can become risky when done excessively or with poor form.
