hey dude! >hugs and kajis <3
i will admit this is where i sort of struggle at the most, but only because i haven't spent the time to adress it, but i will give you some excersises that, with time, will help your dorsiflexion
the first easiest thing i can think of is to either find a step or a brick, then you place the ball of your foot on the edge, and push down till your heel is on the ground. you can hold it there for as long as you feel you comfortably can.
an alternate version of this is to find a wall and wedge your foot up against it like doing a low stomp, then push towards it to stretch out the calf. or alternatively you can place your hands on the wall, slide the foot flat on the ground backwards and then slowly lower your knee as far as you can while keeping your foot flat on the ground, and just do slow deliberate reps of that
you could also do this
find yourself in a relaxed horse stance with your feet a little farther than shoulder width, and then tuck your butt and pelvis. then you shift your weight and turn your hips towards the side you are shifting towards. this will strengthen and stretch the calves, knees, hips, and the muscles in the leg. over time you can try going lower and lower as you feel stronger and more able to do thisPost too long.
