morning workout with a kettlebell

45 minutes is a lot with KBs but you could do:

KB swing/push up ladder
10 swings
1 push up
10 swings
2 push ups
Go up to 5 push ups and pyramid beck down.
This gives you 90 swings & 25 push ups

Take 2-3 minutes rest

Then:
10 minutes of
8 goblet squats
8 KB rows each side

2-3 mins recovery

Then
10 minutes of
5 single arm KB presses each side
5 reverse lunges off each leg
20s plank

You can extend all of these.
Make the push up ladder higher, up to 10 push ups & back would give you 190 swings & 100 push ups.
You could extend the 10 minute blocks to 15 over time
