Make sure to consciously push knees out so they stay inline with the toes as you descend
Bench Press
Points to consider
3x5 @ 45lb
Did 2 additional sets of 2 reps at 50 and 55lb
Elbows don't need to be tucked in at such a tight angle. Try to keep them a bit wider to recruit more support from your chest muscles
Deadlift
Points to consider
1x5 @ 100lb
Warmups: 2x5 at 65lb, 1x5 at 85lb
Keep arms straight throughout the pull. Bent arms won't be possible as the weight becomes heavier.
Think about keeping your lats tight before and during the pull to prevent "shrugging" at the top. Don't pull your scapulas towards each other; keep your armspits pulled in to ensure your lats, not traps, are doing the lifting.
