I was leaning forward a bit.
Forward Lean
...a certain amount is natural. The degree of forward lean is dependent on how you are built.
Fold-Ability and Proportions
Tom Purvis, Physical Therapist, video above demonstrates what is acceptable..
...my squats is, there is a sticking point coming out of the hole when the weight feels much heavier, about 1/3 of the way up.
The Ascending Squat Strength Curve
The sticking point for lifters is in the bottom position; from the hole position to just a few inches up. This is weakest part of an Ascending Strength Curve Movement for the Squat.
Two method will help in the bottom part of the Squat...
1) Specific Strength Exercises
a) Pause Squats: Pausing the weight for 4 seconds eliminates the stretch reflex; thereby increasing strength out of the hole position.
b) Isometric Squats: Isometric and Functional Isometrics from the hole position.
c) Various other types of Paused Squats from the hole position, as well as Paused Leg Pressing pausing the weight at the bottom and driving it up.
2) Power Training: Moderate Load (48-62% of 1 Repetition Max X Sets of 1 - 3 Repetition)
Squats preformed explosively with a stretch reflex/plyometric bounce out of the hole.
Research shows that up to 18% more power is created when the stretch reflex is elicited.
Power is "The Grease" that help maintain momentum, sliding through your sticking point.
