Worked up to a very tough triple. I used elitefts average bands and elitefts light bands for all my working sets. - All of them were to a box below parallel, with a buffalo bar.

Buffalo bar + Avg and light bands - box below parallel

bands x 3
135x3
185x3
225x3
275x3
315x3
365x3
385x3 - The 365 was hard, this set was the hardest I've had to grind in a long, long time. I need to keep doing things like this out side my comfort zone. I could immediately tell that my back, glutes, hamstrings were all going to be sore.

Accessory work:
To stretch things out I did some light good mornings on the buffalo bar 5x5 at 135.

Prone Hamstring curls 3x20
superset
machine crunches 3 x 20

* As predicted the following days my lower body was wrecked.
