What is your “getting back into shape” method? I have always been super guarded bringing a horse back into shape - and sometimes have been guilty of “taking it too slow/easy”. Keep in mind my trails are very super hilly.
My plan was to do something very similar to this - with one or two days off a week - and adjusting based on if his stifle is getting stronger. A vet is involved but gave me a cookie-cutter rehab/fitness schedule.
THE ADJUSTABLE REGIME PENDING:
WEEK 1: walk, 20 mins
WEEK 2: trailride, walk, 30 mins
WEEK 3: trailride, walk, 45 mins, add some short (30 second trots) on trails
WEEK 4: trailride / schooling, 45 mins - 2-3 min trot 2x
WEEK 5: trailride/schooling mix - interval trot sets @ 2 mins
WEEK 6: if we’ve made it that far, see from there.
