Interval walking...

I tried various treatment methods due to my herniated disc in my lower back.

Nothing seems to be working well, and I keep failing...

The doctor just told me to keep walking steadily^^;;;;

Walking every day makes it manageable! Haha

I'm glad that walking is something I can do well.

I've been working hard and doing well for several years..

I wish my muscle strength would increase rapidly, but I'm not sure.

Interval walking is said to be very effective.

Has anyone experienced improvements in strength?

I'm really curious whether interval walking is much more effective than regular walking for improving lower body strength.
