SmartSpot, which has developed an interactive video-based offering for gyms that instructs members how to work out properly, raised $1.85 million from Khosla Ventures and Signalfire, according to TechCrunch.

The company uses 3D cameras to analyze the way a person performs exercises, and provides near real-time feedback about how to get the most out of the exercise. The device is a fixed installation at the gym that includes a large body-sized screen. SmartSpot’s service also tracks the user's reps and sets for weight lifting activities and keeps tabs on rests between sets.

Types of exercises that SmartSpot currently tracks include bicep curl, seated shoulder press, lunges, front squat, bent over row, and hammer curl. 

When the user is finished with their gym session, they can review their data and see how their performance compared to past performance. The screen will also show users a calendar view of what muscles they worked out that week.

Gyms can place a SmartSpot machine near a squat rack, free weights section, or in a personal training room. The entire system costs $4,999 per workstation.

SmartSpot also plans to eventually develop smartphone apps -- the company's hiring page lists descriptions for Android and iOS developers.

Another startup that aims to add digital features to gyms, called GymSnap, launched earlier this week, according to Bostinno. The company will partner with university gyms to inform students via an app how busy the gym is at any given time. The app will also offer information on their school's gym and allow gym managers to send messages to students
