Exercise is encouraged for patients undergoing chemotherapy. However, patients have reduced exercise tolerance / compliance after multiple rounds of chemotherapy.
Per this article, high-intensity interval training (HIIT), also called contrast oxygen, which is one of the modalities we offer at Gym for the Brain, was used to safely improve exercise tolerance without any adverse events.
If you know someone receiving or recovering from chemotherapy, suggest they consider HIIT for improved exercise and faster recovery.
