Finish it with a volley! Serving Aces all the time! Good slice on the backhand to change rhythm! Squash-like-defence on the run!
All those are using continental grip. As much as coaches often teach the forehand as their first skill set for the players using the forehand grip, one cannot deny the importance of continental grip.
To be better at continental, use warming up as one part of the continental practice. Players need to be able to handle the volleys, slice and the smash using continental in the specific tennis warming up. The change of grip between forehand grip (western/semi westen to continental) will make huge differences in seeing a better player or not.
By integrating the continental warm up into the tennis warm up and making it a routine, players will surely be using the continental every training session. This will make them improve occasionally without them realizing it.
The tennis specific warm up may consist of forehand and backhand mini tennis, the slice forehand and backhand, reflex volley and smash & volley. The session can include forehand/backhand with alternate forehand/backhand slice.
Understand that in tennis, the continental is used in more strokes compared to the forehand grip. Then why not practice it early in the beginning of the session everyday.
