I have one flat feet(right) and one high arched feet. The difference is highly visible and my right foot is UK Size 10 and left is UK size 8. This has created alot of problem as I dont have the same amount of dorsi flexion resulting in me falling on my right leg, and thus working right leg have more stimulus and therefore more growth(from quads to glutes,hamstrings and calves). Unless I keep my left foot more forward than the other one and keep place it as straight as possible(as opposed to a slight outward rotation when you have a flat foot). I am only now doing body weight squats for around 15 reps. And I have no idea if continuing this would be safe. Does anyone deal or know how to deal with this problem? Will surgery actually help? And if yes. What are chances of using my legs for hardcore weightlifting(around 3-3.5 times my bodyweight at max genetic potential).

1:01 Best Exercises are Back Squat and especially Front Squat. 1:45 Load Leg Extension with lighter weight, ~12-20 reps. Add more reps each week until 20 reps reached rather than increasing weight. 2:29 Why use Leg Extensions? Good for adding volume rather than doing only compound exercises. 3:28 Hips should be at an angle greater than 90°. Plant butt into seat. 4:22 Point toes straight ahead or slightly in (Outer Sweep).

Jeff, I've been wanting to thank you for some time for the quality of the content you produce (but I never sit still long enough to do it). So now, THANK YOU! I'm new to the KZitem fitness community but have been training in some capacity for 30 years now (GEEZUS that stings when I think about it!) In all my endeavors you are simply one of, if not The BEST presenters, as well as the most researched and credible, active professionals I have ever had the pleasure to learn from. I absolutely devour your lessons and then use your research and references to build on my foundation of knowledge and experience. Though maybe considered irrelevant to most I absolutely appreciate your ability to articulate your points without trashing established misconceptions or trashing others within the industry. The manner in which you address fallacies and then correct and validate your points is masterful! I absolutely respect what you represent and the manner in which carry your channel. And I am truly grateful for you and your content. It has helped me greatly in repairing years (ok, decades) of damage, and been an integral part of my rehabilitation and evolution. So again, Thank you so much!!!

I like leg extensions. When I do the regular leg exercises like squats, Bulgarian split squats, lunges, leg press, my hamstrings and glutes are sore as poop but my quads not at all. My trainer said many ppl aren't like that and tend to lift using their quads. So I like leg extensions to actually hit the quads.

the wrist straps - In all seriousness I have used them for leg extensions once or twice. Pulling myself into the seat very firmly, I find, helps me get the most out of my sets and reps. Where my fingers/wrist start to weaken eventually from pulling into the seat, straps have given me that little extra help. The only reason I don't do it so much now is cos I know people will think I'm dumb for doing it and yes I do care about that. Secondly I don't go so heavy now on extension, lighter and higher reps like Jeff suggested here, as well as isometric holds and very slow negatives.

When I do extensions I've found that doing 100 slow reps low weight with drop set if necessary, to really warm up my quads. Then I'll start around 150 to 200 lbs and do however many reps is possible, and drop set the weight 10-15 pounds until I get all the way down the stack, with this method I grew my legs strong and large within a year
