Is there a knee lift in the Muay Thai leg sweep?

Of course you have to lift your knees. Don't think too much of a difference between sweeping kicks and whip kicks in Sanda, they are roughly the same.

There are three main differences between sweeping kicks and whip kicks:

1. The leg trajectories are slightly different: the power of sweep kicks is from top to bottom after lifting the knees, while whip kicks The leg strength is flat kick;

2. The focus parts are slightly different: the sweep kick focuses on the instep, ankle and wrist, and the lower part of the calf, while the whip kick focuses on the instep;

3. Sweeping kicks are exerted without stopping, and whip kicks are struck quickly and withdrawn quickly.
