Is this gym only trainer-trainee? Can you work out on your own here or is it strictly with a coach? Is there a sauna?

There's coaches at each session that monitor the whole class, monitor progress, provide guidance and motivation while maintaining safety. No sauna, it's not a gym but more a crossfit atmosphere. Trust, you'll end up benefiting if you need some motivation and consistency.

There is no Sauna and it is primarily a class format, 2-3 trainers per group class.
