The Nationalmannschaft trainer is happy with his sides preparations ahead of their trip to South America where they will go in search of their fourth world title
Germany face two final friendlies at home against Cameroon and Armenia before they head to South America for their opening game against Portugal in Salvador.
Concerns over the fitness of Philipp Lahm and Manuel Neuer have been cast aside and Low has been delighted with the attitude shown throughout his squad.
"We have worked on a lot of things and I believe we have made a lot of progress, both tactically and physically," he said.
"Everyone has been very focussed during training and the players are all getting along very well, it's a good atmosphere.
"Philipp Lahm has been training intensively without any problems and will join team training soon.
"Lahm and Manuel Neuer won't play against Cameroon on Sunday, (but) there are still two weeks until the World Cup starts, by which time they will be in form."
Germany were held to a goalless draw by Poland earlier this month but have not lost a game since the 4-3 reverse against USA in June last year.
