I'll need to go sentence by sentence. For example, "Lifting heavy objects or weights" becomes "Lifting|Lifting|Liftingheftingobjects|objects|stufforweights|weights|loads". Wait, maybe some words can stay the same if they don't have enough synonyms. But the user probably wants all words modified. Hmm, maybe for "objects" or "weights" use synonyms like "items|masses|weights".
Now, the next sentence: "Practice proper lifting techniques" Tummy Tear Real Video
Then "Maintain good posture and muscle balance" → Preserve positive alignment and muscle equilibrium I'll need to go sentence by sentence
Also, check for any possible errors where substitutions might change the meaning. For instance, "muscles" to "body" might not be accurate, but "core" is a better synonym. Similarly, "tummy" in "core|tummy" is okay as a synonym for abdominal region. Tummy Tear Real Video
