Great app!!! PROS: It has enabled me to fit in short bursts of exercise throughout my busy day. The music, voice instruction, fitness model demos, variety of workouts and video quality are a winning combination. The fitness models can seem a bit robotic but I actually think its an interesting effect--feels more like a video game. CONS: There are a few technical glitches. Occasionally the video stalls or the audio goes out, but then I just choose a different video. And when I reported it to the Zova team, they said they were working on resolving those issues. OVERALL: Im excited about this app and hope it will help keep me more consistently active this year.
