Yesterday I watched a TV 'program' (programme) 'which is' (niepotr) called „Wipeout”.
Therefore 'there' THEY must be athletic and persevering because the winning depends on their strength and agility. Now I want to present 'better this program.' (nie, to jest zle - napisz explain the idea of this programme better)
Some of them are even sportsmen or sportswomen and they are true 'professional' (tutaj l. mnoga, bo wczesniej piszesz 'they'). But this programME is also for amateurs.
So they must not only have an athletic body but also a 'big' (to jest za dziecinne slowo tutaj, mowimy 'high level') level of concentration. Therefore they must also have a strong personality (jedno sie z drugim nie laczy, ktos ktory mysli, nie od razu znaczy ze ma 'strong personality').
There are many kinds of them. Many competitions are connected with water- in my opinion 'it' (dlaczego 'it' jak wczesniej piszesz many competititons') 'is' (l. mn) the most difficult because they require a really 'good' (zle slowo, tutaj HIGH level of) concentration and equilibrium. 'And'# (nie za bardzo stosowne zaczynasc zdania z 'and') sometimes there are the most thrilling.
Apart from that, the trait of this kind of competition is that in each of them there are many funny situations which 'divert' (zle slowo - divert of czego?) the audience.
