[3][4] While still in France Charles Lecour watched English boxing on a high level when he was a spectator of an official match Owen Swift vs. Jack Adams in 1838.

[8] In order to establish Savate as a fair sport[9] Michel Casseux had dropped a number of fighting techniques that henceforth had been considered unsporting.

[18] Following his boxing training he returned to France where he opened his own gym in Montmartre [19] and introduced boxing gloves [20] which now have a unique meaning in Savate since they display (instead of belts as in many Asian fighting systems) the ranks [21][22] and hereby symbolize that participation in competition is mandatory for a Savate student who wants to advance beyond beginner's degrees.

[23] He and his brother Hubert Lecour (1820–1871) also organised public demonstrations of French Boxing[24] and their schools were prosperous.

[26] Charles Lecour's open-minded and pragmatic approach to martial arts and his according integration of boxing techniques into his inherited fighting style made him an early predecessor of Bruce Lee.
