Positives

• TRX appears as slow functional training for patients trying to rebuild strength without jumping straight into upright cardio or heavier exercise. Reddit.

Negatives

• Exercise tolerance can remain fragile; the same kind of patient update describes winded walking, coughing, dizziness, palpitations, and days when sitting still is the smartest choice. Reddit.

Hurdles & Side Effects

• Patients with POTS or orthostatic intolerance often need rehab-style progression, heart-rate awareness, and very small starting doses before adding more demanding suspension work. Reddit.
