To cycle your training regimen, start at a moderate intensityon each set (around 75 percent) and build over the course of 3-4 weeks to 100 percent or failure.
Options to look for include adaptive cruise control that can automatically maintain a set speed and interval on the highway, and high-intensity Xenon headlamps with Active Curve Illumination that can help illuminate the road at night through curves.
Like all Garmin products, the BarkLimiter Series is simple to use, with a set-it-and-forget-it "autorise" function that automatically programs the stimulation intensity level based on the barking behavior of each individual dog.
