RDL TBH
deadlift can't reach bar with straight back
Keep your legs straight and try to get in position for a stiff legged deadlift. If you can't touch the bar, it's a hamstring/glutes/lower back flexibility issue. Do stretches everyday to fix this.
Drop into the third world squat position. If you can't touch your quads to your chest, it's a hip mobility issue. In that case, practise third world squats.
practice RDLs. you need to practice your hip hinge starting from the top and hinging down as low as you can go without rounding. over time you'll be able to get lower and lower. (weighted eccentric stretching is extremely effective)
Pushup
5x5 (Pyramid, Hourglass, Reverse Pyramid)
Really focus on the muscle contractions as you do the pulling motion. Back to the basics
Deadlift
How about back?
When lifting make sure to ask the question how can my body support this weight
You reap what you sow
Preparation stage
1 Lift with the lats up the knees
Use hamstring as stabilizer
bend bar over back/elbows far back
warm up with no weight to get used to the movement
Need to lean back
Get a comfortable stance (Lock shoudler and place weight on there kinda like the other lifts)
Foot slightly tilted, mostly straight
Low Lats
