Buongiorno Elisabetta ' I normally rise at 7am ' means ' I normally get up at 7am ' - same thing [alzarsi]. To ' rise up against ' something is a different use of the word. The basic meaning of 'rise' is 'to go up' : bread and cakes rise when they are baked in the oven ; a very high building is called a 'high-rise' ; to rise in your job means to move up the ladder in that employment, etc.

To rise up: to go against something bad, like a dictator or an oppressive government. To get up: to wake up and get out of bed. Good luck!

'Get up' is normal, everyday English. Mi alzo alle 7 = I get up at 7. 'Rise' can have the same meaning, but it is old-fashioned and formal. We don't usually use this verb in this sense in modern English. Prices rise. Bread rises in the oven. The sun 'rises' in the morning - but people 'get up'.
