Answer for Adding power to forehand

I think he your coach is correct if you are struggling to get power. Of course you do still need to have a good contact on the ball to produce a bit of topspin and with practice it will improve for sure. It’s hard to say that you make it your normal forehand because you need different shots at different times and situations but it will definitely help if you can learn a more powerful and aggressive forehand to win more points with. But still be able to play with spin and control when needed
