My first impression.
Yesterday evening I have assembled the Freespine machine - the procedure wasn’t complicated.
I had one trial session with the Freespine within 4 - 5 minutes, it was surprisingly smooth and easy to exercise,  it was like effortlessly gliding through the air, I felt no physical workload, however I was hot, although it was in the cold room.
The next day my back, abdomen, shoulder, arm and leg muscles ached as after workout in the gym. And it was just 5 minutes of light workout on Freespine!
 I decided to follow the recommendation for beginners: not more than 5 - 10 minutes in the morning and 5 - 10 minutes in the evening  within the first couple of weeks.
