Lazenby was the most physical Bond. Without shaky-cam or modern fight choreography, the fights in that movie are fast and brutal.
When he throws a punch it looks as real as any movie from that era.
Excellent but Connery and Shaw threw down so well on a train in "From Russia With Love" I still get amped when seeing it. Real fights are a dual battleground of physicality and mental chess. That one was actually paid homage to in "Live and Let Die" - a rare call-back in the franchise outside of running jokes.
