The Payoff

    Do first

    Resistance training

    Strength and muscle mass track closely with independence and metabolic health later in life. Two sessions a week covers most of the benefit.

    What the evidence supports

    Progressive resistance training improves strength, muscle mass, physical function and metabolic health. These are important determinants of independence as we age.

    Most relevant when

    Strength, lean mass or functional capacity is low — or your current routine is almost entirely cardio.

    Keep in perspective

    Associations with lower mortality are encouraging, but they do not prove that lifting alone causes a longer life. The functional benefits are much more firmly established.

    Safety

    Technique and progression matter, particularly with pain, osteoporosis, cardiovascular disease or previous injuries.
