Alright So I just bought this beautiful mare with great stats and all of her actuals were over 200. I lowered her diet to 10/10/10/10 to raise her endurance faster, but this lowered her strength which I understand. When her strength reached 200 I put the diet to 35/15/35/15 and then trained in driving to raise her strength, but now her strength will not rise in any kind of training. I've even put her diet at over 100% to try and gain strength but that did not work either. I would love to work her in 3-day eventing but she needs more strength.
