If the body is moving with poor control, adding more intensity does not automatically help.
Before chasing harder workouts, it is worth learning a few simple positions that make movement feel more organized and less sloppy.
Movement / Card lesson
Before you chase harder workouts, learn to move without dumping chaos into your spine.

If the body is moving with poor control, adding more intensity does not automatically help.
Before chasing harder workouts, it is worth learning a few simple positions that make movement feel more organized and less sloppy.
A useful movement rule is simple: the trunk provides control while the hips and shoulders provide motion.
In plain language, the middle of the body should not feel loose and chaotic while everything else is trying to work around it.
Quick check
Try this
Before a lift or a hard rep, use the same short setup: feet planted, ribs stacked over pelvis, light abdominal brace, shoulders relaxed, chin neutral. You are not trying to freeze the whole body. You are trying to start from a cleaner position.
Try this
Spend short bits of time in a supported squat if your body tolerates it. Hold a doorframe or counter if needed. Think 30 to 60 seconds at a time, not heroics. The goal is to reintroduce range, not push it.
Key idea
Movement usually gets better when you organize it before you intensify it. Start from a cleaner middle, use supported range, and let control come before ambition.
Stop any exercise that causes sharp or worsening pain.
