My horse turned 2 last month, and he has just been started very lightly undersaddle, so here is what my week has looked like in the past month.
Monday Groom, tack up, 10-15min ride. Untack, groom, fly spray.
Tuesday don't go out
Wednesday Groom, lunge, and or ground work, fly spray
Thursday don't go out
Friday Groom, tack up, 10-15min ride, untack, groom, fly spray
Saturday don't go out
Sunday Groom, ground work, stroll along the trails, fly spray
Also, if there are people at the barn, and I have my horse, I usually make him patiently wait there until I am done.
