💡 Benefits of Quad Extension (Machine)
Isolates all four heads of the quadriceps and is easy to progress with small weight increases. It is also a good option for people who cannot squat heavy.
📈 Sets, Reps & Programming
Do 3 sets of 12 to 15 reps with a one-second squeeze at the top. Adjust the pad above the ankles and the seat so the knees line up with the machine pivot.
⚠️ Common Mistakes to Avoid
Using momentum to kick the weight up
Lifting the hips off the seat
Slamming the weight on the way down
✅ Pro Tips
Pause for a second at the top and squeeze the quads
Lower the weight slowly for two to three seconds
🛡️ Safety Notes
Keep the load moderate if you have knee pain, and adjust the pad above the ankles. Stop if you feel sharp pain in the front of the knee.
