A small French study found lifelong exercisers over 55 had more physiological reserve. Not more muscle. Here is what that means and what it can't say.
A review of 480,000 people links regular stair climbing to fewer heart deaths. What the numbers say, what they can't, and how to start.
A study of more than 5,000 women aged 63 to 99 found stronger grip and faster chair stands linked to significantly lower death risk over eight years.
A review of 15 studies finds weighted vests help older adults mainly when worn during exercise, not lounging, and only when the load is added slowly.
A review of 11 trials found short daily bursts of movement lifted cardiorespiratory fitness in inactive adults, though strength gains stayed modest.
A UChicago study of frail older adults found that lifting your pace by about 14 steps a minute, not walking further, improved how far they could go.
A 160,000-person Lancet review found most of walking's benefit arrives near 7,000 steps a day. The famous 10,000 target was a 1960s ad, not science.
A meta-analysis of 2,408 older adults found Tai Chi improved balance and eased fear of falling. One fall-confidence measure, though, did not budge.
A 30-year study of 147,000 adults found strength training's biggest benefits arrive by 90 to 120 minutes a week. After that, the curve goes flat.
A Penn State trial found four minutes of daily strength moves measurably improved balance and mobility in older adults within 12 weeks.
A University at Buffalo study of women 63 to 99 links two ten-second strength tests to significantly lower death risk over eight years of follow-up.
A Penn State study found that just four minutes of daily strength exercise improved balance and mobility in adults over 65 within 12 weeks.
