My sport activity

When I was a child, my father teached (taught: past tense) me (how) to play football. From (with time we use "Since", "Since that time") that time I couldn’t live without regular exercises.
("During different times" or "In different phases") In different times of my life I (have) preferred different kind(s) of sport activity.

I often played football when I go (went: past tense) to school and (also when I) studied at University. Then I began to do ("practice" sounds better) Kung-Fu exercses ("excercises" is not needed) two times ("twice" sounds better) a week. At the same time I (also) went to a swimming pool.

I like to go out (of the) a city for the weekend so (that) I (can) ski in (the) winter. Fortunately my wife likes sport too. We always do exercises together and I’m very happy about it.

My sporting activity

When I was a child, my father taught me to play football. From that time onwards, I couldn’t live without regular exercise.

At different times of my life, I preferred different kinds of activity. 

I often played football when I went to school and studied at University. Later I began to do Kung Fu exercises twice a week. During the same period, I went to a swimming pool.

I like to go out of the city for the weekend so I ski in winter. Fortunately my wife likes sport too. We always do exercises together and I’m very happy about it.
