start by playing slow, a little at a time, and eventually, they will strengthen. it takes time to build them up. its just like exercise, start of slow a little at a time, and increase the amount of time u play each day. like start of playing 1/2 hour day, then 1/2 hour 2x a day, etc. and when they hurt, just push a little more each day. you will get there, but it takes time. and practice, so don't give up. it takes dedication, desire, discipline. good luck. u can do it.
