I know the "limited turnout" thing all too well. My horse is moving to his summer barn tonight. He's only getting out 1-2x a week now due to the weather and b/c the paddocks are nothing but ankle deep mud. He is 2.... that's not enough for him. If I didn't lunge him before I got on him, I'd probably die lol Not that he bucks or does anything bad, he just has a LOT of pent up energy and I'd be stupid to just saddle him and hop on. So, I get it. I hate lunging tho and I ONLY do it when I have to, to prevent dying lol Thankfully, he's about to have summer turnout in a large grass pasture.
