• Should you go heavy on leg extensions?

  Focusing on form over weight is crucial with leg extensions. Going too heavy poses a greater risk of injury. Even without this risk, choosing a weight that is too heavy means you're more likely to rely on momentum rather than muscle to move the pad. Opt for a weight that is challenging but still allows you to do a controlled, smooth leg extension.

• How many leg extensions should I do?

  The exact number of reps and sets you should do leg extensions for will vary depending on your goal. A good number to aim for is 3 sets of 8-12 reps. As you reach the top range of these reps, increase the weight to make it more challenging.
