I feel obligated to post this since this problem hindered my progress for years.
I’ve fixed this problem pretty much. I don’t have perfect flexbility, but I have adequate flexibility to perform deadlifts/squats using correct technique.
Heres what I did.
I suggest you plan flexbility/foamrolling sessions throughout the week a long side your workouts until the problem gets corrected…
SO for flexibility/Foamrolling work…
First you need to loosen up any scar tissue in the muscles.
Foam roll your quads, IT band, and adductors.
Use a tennis ball/lacrosse ball on your piriformis, calves, and the bottom of your feet. You could probably also visit an ART practitioner and get better results.
heres a video that covers pretty much what I did to loosen up the muscles.
Then do static stretching. You have to realize though that you should not be forcing stretches. You need to teach your body how to gain back flexbility…It’s not about inflicting pain… you need to teach the muscle to relax and gain ROM…Breathing and relaxing is critical…
static stretch your rectus femoris, hip flexors, piriformis. first three here.
static stretch your calves.
static stretch TFL.
I also stretched my low back. I just did that by keeping my knees bent in a regular hamstring stretch and let my arms hang down. don’t stretch the hamstrings.
Now…For Training
Do a dynamic warm up before you do lower body training. I recommend Joe defrancos agile 8…Look it up on google.
As far as exercise selction, you need to emphasize hip extension(hips pushing forward like a deadlift) rather then knee flexion(squatting movements). 45 degree back raises, DB Step ups, deadlift variations, GHR, reverse hyper, pullthroughs). In all these movements, Keep your abs tight and your torso straight and Squeeze your Glutes to finish the movements.
You may also want to do glute activation exercises before and in between sets. The purpose of this is to teach your glutes to fire – you can’t strengthen a muscle is if it doesn’t know how to fire. side lying clam, X band walks, and glute bridges are good choices.
You need to train the abdominals to act as stabilizers. The paloff press and ab wheel/ball rollouts are the best exercises in this regard but plank variations are a good start – you must stay tight in the plank…any deviation is a fail(2 min on front plank and 90 sec on side plank are standard times). drop the crunches/sit ups as they mainly train the hip flexors. Strong hip flexors are needed to squat big weights but chances are if you have tight hamstrings then you don’t need more hip flexor work.
Finally when you do get back to Deadlifting from the floor and squatting. You need to emphasize PERFECT form EVERY REP. You need to end the set before your form breaks down or else your CNS will store bad motor patterns and you will actually teach your body to compensate and fail rather then to succeed. Look at the best lifters in the world. They end the set early. How many times have you seen or heard “He made that look easy. He could have done more reps with that weight”…Yeah he could have but he would have used bad form to get them, and he would have never made it to where he has now if he listened to you…
I’m not an expert in this field, but what I did…did work…
I’m in the process of correcting my Upper body now. I have a ton of issues since I’ve played baseball/football since I was a young kid which has probably caused a ton of issues.
