I currently do horseback riding (English Equitation mostly. I'm learning a little bit of dressage and starting to get into jumping), yoga, YouTube Krav Maga workouts, and walking my dog.
When I do my horseback riding lessons at the NFP, I tack up and down and ride my horse. If you aren't familiar with tacking horses, it requires a lot of strength and endurance, especially if you have to groom them first, which I have to do with Kadena (the horse I ride) as she often isn't used in lessons before I come. The procedure often goes as thus: using a hoof pick to clean out debris in the hooves (you must get the horse to give you their feet first. You must hold the hoof in one hand, clean it with the pick in the other), with horses with large white areas such as Kadena - you need to use charcoal to lift any noticeable stains then use a curry brush to dig out dead fur, sand, dust, hay, etc. A hard brush then sweeps this debris away. This is followed by a soft brush to smooth the hair. A comb or hair brush is used to detangle the mane and tail (my favorite part.) That entails grooming. To tack, I put on a basic saddle blanket and even it, then a fleece saddle pad followed by the saddle, which weighs about 30 pounds (it's heavy.) The girth is strapped onto one side, I walk over to the other and strap it to the saddle on the other side, then tighten accordingly. Since Kadena wears a nose strap, I take off her harness, affix her bridle that way, then adjust my stirrup leathers, then I put her harness on her bridle hook and take her out to the arena to ride. It takes about 30 minutes. Good strength training. I also stretch out her legs before I ride her so she doesn't injure herself and stretch them after once I've got her tack off.
