I have been going to the gym for the last 2 years and have gained around 15kgs (was 65kg before). My bowling speed and strength have increase but now become stagnant. Should I be focusing on increasing lean mass up to 90kgs, or focus on improving strength and bowling specific exercises ? Also can you mention those exercises that I should be doing in order to reach speeds of 135 - 140kms ? though any help or opinions or any kind of views are really appreciated.
