Your routine takes you less than 60 seconds? What exactly is that if I may ask?
You may! Two movements, if you please. It will take me at least 10 times longer to describe than it takes to do, and the notes are important.
1. Facing my front porch railing, I put one foot up on it - about hip height, so my leg is parallel to the ground. I keep the other foot at a 45 degree angle for stability. I reach to touch the outstretched leg's toes with the same side hand, then the other side hand, then both hands together. It's your basic hamstring stretch. The "one side, then the other, then both" is an example of "prying", a technique I learned from Pavel and which we teach at Flexible Steel.
Then, foot still on the railing, I stand up straight, turn the other foot to 90 degrees and face 90 degrees away from the outstretched leg, and tighten my glutes and drive my hips forward. This is effectively a 1-legged side split for the raised leg. If memory serves, there's a picture of Pavel doing this, with his foot on a chair (?), in Relax Into Stretch. I make the most out of it by clenching my glutes and driving my hips forward, which is something you need to do in a side split.
And I repeat on the other side.
Important Notes: It is _most_ important that you don't pick a height where you have to throw your leg up to get it there, and even worse would be using your hands to put your leg up. You must pick a height where you can, calmly and slowly, raise your leg above the desired height and gently put your foot down. This is easy stretching, mobility, relax, aaah kind of stuff. I'm often doing it within a few minutes of getting out of bed in the morning, and that's not the time I prefer for hard stretching.
For the raised leg, you _must_ flex your ankle (dorsiflex); you _must_ keep your knee straight. If you don't do both of these things, you won't get a stretch where you want it.
If you want to use spine flexion instead of a hamstring stretch to reach your hands to your foot, or even to touch your head to your shin, you may, of course, but it's good to be aware of what you're stretching. I'm interesting in stretching my hamstring so I try to keep a fairly tall posture and bend at the hip (hip hinge) or at least bend first at the hip and only flex my spine once I feel I've exhausted hip flexion and hamstring stretch.
This also works at different heights, even with both feet on the ground. When the leg you're stretching is on the ground or low, it hits the hamstrings more; when the leg is above parallel, it's already more stretched and you will stretch your back more. I like it with the leg close to parallel best. E.g., my kitchen countertops are higher than parallel for me, still low enough that I can lift my leg and place it there comfortably, but I don't like the stretch I get as much. OTOH, I like this one a lot with both feet on the ground as a hamstring stretch, but you can't do the second part and work on your split unless you're at least close to parallel.
You can also turn the foot on the ground to point in the direction in which you're facing and, if you know what you're doing, you can stretch your down leg's hip flexors this way, just by keeping a really tall posture and clenching the glute on that side.
2. And then I do that things where you swing your arms around as you twist your torso, letting one arm hit you at the back, around the kidney area, and the other arm hit your upper chest.
