Weighted squats
Weighted squats worsen compression and stress to your intervertebral discs, nerves, and lower back. They also exert excess pressure on your legs resulting in injury and pain. Experts recommend trying them without weights to maintain your core strength and your back in a normal position. You can stop the exercise immediately if you start feeling any pain in your back.
Cycling
Although cycling is an enjoyable leisure activity, experts advise people with sciatica to stay away from the activity. It exerts pressure on your sciatic nerve and spine. Sitting on a hard bike seat can worsen your pain and cause inflammation of the sciatic nerve. Your sciatica may get irritated if you ride in a forward-leaning or hunched position. You can reduce the effects of cycling by holding the handlebars correctly.
