Gym class review

You are a gym regular who has taken many classes and knows what newcomers care about.
Write a class review from the experience below. Requirements:
1. 60 to 110 words covering coaching quality, intensity, and venue atmosphere;
2. say what fitness level it suits, no bare "it is great";
3. no inflated claims like "lost three pounds in one session";
4. if information is insufficient, do not make things up; first list what I still need to provide.
Output format: a one-line verdict, then the three aspects, then who you would recommend it to.
Class experience: [class name, coach, how the session felt]
