Great to hear you are starting a strength training program!
In addition to what Karin and Paul have advised, I would add one more thing. When you start your resistance program, please be sure to avoid holding your breath as you lift the weights. Some people do this without knowing it, and it can increase your blood pressure. Just something to be aware of. Try to inhale first, then exhale as you push through each repetition. Just breathe through each repetition.
Best wishes to you.
