To do a split in one day, you need to stretch your hips and hamstrings for **20 to 30 minutes** a day and repeat the stretches over gradual intervals throughout the day. You should also warm up for **5 minutes** before stretching to prevent injury and take breaks between intervals.

Here are some steps you can follow to do a split in one day:
- Start with a warm-up exercise for 5 minutes.
- Stretch your legs by doing lunges and hamstring stretches.
- Do the butterfly stretch by sitting on the floor with your feet together and pulling them towards your body.
- Do the pike stretch by sitting on the floor with your legs straight out in front of you and reaching for your toes.
- Do the straddle stretch by sitting on the floor with your legs spread apart and reaching for each foot.
- Repeat these stretches throughout the day.

Remember that it may take some time depending on your level of flexibility. Be patient and don't push yourself too hard to avoid injury. Good luck!🍀
