Now we're playing 16th beats 70 BPM could feel too fast for you. If so slow down your metronome to 60 BPM.
Remember to always have your metronome running whenever you're ready to keep time. It's fine to turn off the metronome while you're working out the rhythm, but turn it back on again when you're ready to put it into practice.
In each exercises video I'm always playing each rhythm twice round in a circle. When you can do this, you're ready to move on to the next exercises.
