Online Tennis Instruction (OTI) provides tennis training through two primary channels: digital video coaching programs and in-person transformation clinics. The service is based in Schwarzenbek, Germany, and operates Online Tennis Instruction GmbH.

What it is

The vendor describes the OTI Method as a training approach centered on personalized video feedback. This feedback is provided whether a student engages with online training programs or attends one of the OTI clinics. The service aims to help players improve their serves, forehands, and backhands by identifying technical problems and offering solutions.

What the vendor says it includes

According to the product page, the training involves a unique analysis process. The vendor says this process filters out elements of a stroke that, once fixed, result in quicker improvements. The vendor states that this approach is designed to avoid confusion from too much information, which the vendor says is common with standard technical instruction.

The vendor highlights that instructors are OTI Certified and have received intensive training. For in-person clinics, the vendor says instructors provide instant video feedback on the court. To facilitate this, the vendor notes that the company hires hitters and feeders, allowing the instructor to remain next to the student rather than on the opposite side of the net.

The vendor offers several types of in-person events:

  • One-day serve transformation clinics.
  • Two-day technique transformation clinics.
  • Weeklong clinics in destination locations.

These clinics are reportedly offered in many locations throughout the United States and Europe.

The product page lists testimonials from club players who claim improvements in their serve consistency, forehand power, and overall rating. For example, one player states their first serve reached 115mph, while another claims to have become the number one ranked 3.5 player in Texas. The vendor includes a disclaimer on these testimonials stating that individual results may vary.
