Sorry so slow…
As suggested for core/hips/shins:
For hips, get a lightweight tension band. You want it to be light so that you can have full range of motion when using it. No more than 10-20 pounds.
Start with 1 set of 10 each of these on each side. After 2 weeks, increase to 2 sets of 10 each. Do these 4-5 times per week. Take this seriously, and you will get better.
Side Plank 1 set and then 2 sets after 2 weeks (start with 30 seconds. If it is too easy, do 45 or 60 seconds. Keep good form. It should feel slightly uncomfortable at the end of the time, but not painful):
Eccentric Heel Drops:
Raise up on both feet and SLOWLY lower down on one foot. Do 1 set of 10 on each side, and after 2 weeks, go to 2 sets. Lower down SLOWLY, that is the part that is exercising you.
Single-Leg Knee Bends:
Stand on one leg. Stand tall as you lower down into a squat. Push into your heel to come back up and repeat. Bend knee to the point of instability, not beyond. Go deeper as it becomes easier.
Doing core work will make your running feel better. There are also stretches you should do, but I don’t want to overwhelm you. Start with the core. Commit to it.
Split them in half and alternate each half of the exercises every day. Or do them all 4-5 times per week, and skip some days to rest. Whatever works so that you will keep at it.
