If you’ve ever been to a gym after a long absence or started up a new exercise routine as part of your New Year’s resolution, you have a good appreciation for the importance of gaining and maintaining fitness. The same concept applies to your horse when you put him back into training after giving him the winter off, after a layoff from an injury, or when starting a young horse under saddle. Unfortunately, many horse owners and trainers are concerned only with working their horses over obstacles or schooling maneuvers specific to their sport, rather than ensuring their horses are fit enough to perform such tasks.
