Excellent professionals. They give you an initial assessment and adapt the sessions to your physical abilities and goals. They manage to instill an enthusiasm for exercise that goes beyond the sessions themselves, and in just a few months I've experienced a real physical improvement (weight loss, increased muscle tone and flexibility) and acquired healthy lifestyle habits that make me feel much more active and energetic.
I thought personal training was overkill, but after trying it, I realize it's essential. It's changed my life!
So I recommend it 100%.
