If you have just Left Hook, put it on and raise the number as high as you can -
2 in this case. A punch works nicely as well.
I'd say apart from a bat, with your stats you can easily take on a fox for starters.
Just do like in the video, you don't even have to constantly tap, just tap it right after you hit every time. You'll see the move has a bright stroke around it - that means it's queued.
Maybe have some yarrow on you for the scapes and cuts. They can add up and form harsher wounds.
PS: The more you do it and get confident and the higher you raise your stats, eventually you'll be killing beavers, boars and then deer and such. But take your time to get used to it :)
