Heart rate

I joined a gym a few months ago. At the end of 30 minutes on the treadmill.my heart rate  is between 125 - 130. Should I wait for it to come down before  i start on a 30 minute workout on the weight machines the weights? If yes, how far down?

You didn't give any info. on your physical shape and any health problems.
I'm 66 and 85% of my max. heart rate is 150 so at the gym I do weights first
and cardio last and my heart rate is up from the start of my complete workout.
In short if your in good shape and your doctor said it's OK to workout then keeping your heart rate up throughout the workout is OK it's called Interval training.

P.S. You burn 30 percent more fat from doing cardio after a weights session as opposed to cardio on its own.
