Maria I've started training with David because I suffer from a bad fibromyalgia and anxiety disorder. My goal is not to lose weight, although in only 20 days without a strict diet I have already lost 2.5 kg. My goal is to get healthy and tone up a bit, but the weight and fat loss were also welcomed!! In only 10 sessions my fibromyalgia has never been better and my anxiety levels have dropped considerable too. I don't have chest pains as often as before because my heart is also getting stronger. David changes the sessions every time, working with my capacities and age -I'm a 45 yrs old woman with sedentary life- combining weights, cardio and high interval exercises without allowing me to exert myself. This makes the workout fun and challenging but within my limits. Every week I'm feeling stronger. I don't get out of breath now or have chest pains when going up the stairs to catch the train. We exercise outdoors in the park which is also equally rewording and he even sends me encouraging videos or nutritional tips during the week. I can't recommend it enough!
