Here is how u tie the boxing band

Biki Bora shows you how to tie up the band around your hand. See earlier blog also on this.
You can run a few extra rounds over the thumb, to protect it further, if the band is very long.
The knuckles must be covered properly. Some bands tend to open up. That is fine for those with broad hands. Those with smaller hands, like women, may need to buy softer band which grips around their hand more firmly.
