To the Editor In their timely and comprehensive article discussing exercise interventions to aid in cancer treatment, Iyengar and Jones1 describe the promises and pitfalls of current exercise research. This description includes the common issues of measuring and quantifying exercise dose, an area plagued by a reliance on self-reported data and often quantified by step counts, accelerometer data, and metabolic equivalent task hours per week. However, an important area often neglected in exercise and cancer research is the quantification and use of weight training, specifically intense and heavy weight training during cancer treatment and survivorship. Along these lines, within the cancer world, exercise has seemingly become synonymous with walking, aerobics, or jogging.
