Keep training but cut volume and intensity; stress hampers recovery, so aim to maintain rather than push records.
The quick answer
Training under stress can help your mood, but heavy life stress slows recovery, so shift from pushing personal records to maintaining. Reduce volume and keep sets 2 to 3 reps in reserve, prioritize the compound lifts that give the most return, and keep sessions shorter. Sleep and nutrition matter even more when stressed, and a lighter, consistent session beats an ambitious one you skip.
How to think about it
Maintain, do not max
Chronic stress raises fatigue and blunts recovery, so this is not the time to chase records. Keep the weights moving with a few less sets and 2 to 3 reps in reserve, which preserves your strength and muscle without digging a hole.
Trim volume, keep the basics
Cut the accessory fluff and keep the big compounds that give the most stimulus per set. A shorter, focused session is easier to actually complete when your mind and energy are stretched thin.
Double down on recovery
Stress steals sleep and appetite, which are exactly what you need to recover. Protect 7 to 9 hours of sleep, keep protein and calories up, and use the workout as a stress outlet rather than an additional stressor.
Do this
Lower the volumeDrop a set or two per exercise while stress is high.
Keep reps in reserveTrain 2 to 3 reps short of failure to limit added fatigue.
Focus on compoundsKeep the big lifts and cut accessory clutter to shorten sessions.
Guard sleep and foodProtect 7 to 9 hours of sleep and enough protein and calories.
When to see a professional
If stress brings chest pain, a racing heart, or dizziness during exercise, stop and see a doctor before continuing to train.
