Saying Ga'al Yisrael with Leader or Amen

The prayer leader should say out loud the blessing preceding the amida (ga'al yisrael for shacharit; ha'melech bi'chvodo for ma'ariv). If you:
  • Are up to where he is in the prayers, say the last blessing with him (and don't say amen but do say amen in ma'ariv).
  • Pray slowly and will not be able to join the minyan for saying the amida, you should start earlier than the minyan and catch up at ga'al yisrael.
