Well I can go through horse by horse.
Opal is half leased but kelly is still in college so right now she gets about 2h work/week, will be about 3-4d a week with about 1h/workout on average
Duke is half leased as of this month. He just saw the chiro and is back in riding shape yay! He's getting about 4-5h a week between myself and my half leaser, however he tends to need more walking warmup bc he is a draft cross so it turns out to be about your average 3-4h of work a week when you take that out.
Sky is rebuilding muscle in his power hind end from last season's hunter pace and a massive chiro and myofascial adjustment so he's doing light to moderate work about 1-2h a week mostly longing in side reins right now with light riding one day for about 30 min mostly trot. His ideal workload is 4-5d a week at 30-45m of steady trot with a little canter and one or two days of jumping workouts.
Lucky is coming back into work sound (yay!) and gets 45m - 1h of reiki before riding, and then about 15m of longing and then 15 - 30 min of riding at walk and trot 1-3x a week building up as his back permits. Right now he's rebuilding muscles from a few major back injuries so fingers crossed all goes well and he can do 3-4d a week at 20-30m a workout!
Ridge is my trail horse but we play on the trails a few days a week esp when it's warmer. Right now we alternate days acting like a spaz on the longe, with riding (i say trot he says bunnyhopcanter******edness if we are in the ring) and trail time starting this weekend yay! He's a semi-retired arab off the track and does great at trails which is his main job these days so between his breeding and his job he gets less than the others but we do camping trips where we will ride for 6-8h a day several days in a row (with every 3rd day off) for two diff weeks in the summer so I make sure he is in shape for that.
Between living at my farm and some days working from home I get to ride quite a bit and with 2 of my guys half leased they will all get 3-5d a week of work based on each horse's needs!
(my other two are babies and get limited longing work and training a few times a month)
