If I understood Josef correctly when I first read the Titan challenge, these would be top of the minute swings repeated 3 times.

For example
0:00 2 swings
1:00 4 swings
2:00 6 swings
3:00 2 swings
4:00 4 swings
5:00 6 swings
repeat series one more time.

The following week add another series...4x2,4,6. Continue to add a series a week until you get to 8 series. After that drop back to 3 series but add a rung, 3x2,4,6,8 for instance.
