Could you maybe find a school with a different approach to Kindergarten? My first two only did half days and for my last it switched to full day. But they had 3 recesses spaced throughout the day laced with academic desk work, learning and play stations, lots of music and dancing and a full 30 min of rest time. And of course no homework other than reading to or being read to at home. This is a Catholic private school with very good educational outcomes. The principal caved to parental pressure for full day, but she made sure it was developmentally appropriate once they switched. You could do a year at a private Kindergarten and then switch back for first grade. My brother who is now a radiologist and I (law degree) have managed to get by without an intense year of Kindergarten. We started in 1st grade. I would keep an eye on the gym program too. Sounds pretty harsh.
