Trainers are great, push while teaching proper technique, and create a welcoming atmosphere. The gym is welcoming, friendly, supportive, and motivated. It is not for the faint of heart but very rewarding when a class finishes. The coach is patient and demonstrates lifts to ensure correct form. The gym allows bringing a baby when no one can leave them. Consistent effort shows results sooner than thought.
