I read a roundup this week with three claims that stuck to me. Wearables are still number one. Strength has a sweet spot at 90 to 120 minutes per week. Creatine built muscle in middle-aged adults even without structured training.
I disagree with parts of all three. That is why I kept reading.
Here is what I take from each.
Wearables are number one again, so what
The American College of Sports Medicine put wearable technology at number one for 2026. This is the 20th year they have run this forecast. The category covers watches, bands, chest straps, rings, glucose monitors. Source: ACSM top fitness trends 2026.
I train with a Garmin watch and a Garmin Cirqa. Both record fine. I have a bunch of readings at this point, resting HR, HRV, sleep, load. The data is solid. My issue is different.
Sometimes the data says I am tired and I should train anyway.
I have had mornings with bad HRV, heavy legs, red recovery scores. I laced up, did 10 minutes easy, and the body came around. I have also had green mornings where the first kilometer felt awful. The watch measures. It does not decide for me.
My rule now is simple. I look at the numbers, then I start the warmup. The warmup gets the vote. If heart rate spikes 15 beats over normal at easy pace and stays there, I cut it. If it settles, I do the work. That has saved more sessions than any score.
What I keep from the trend: overnight resting HR, HRV trend, and pace against heart rate on easy runs. I ignore the rest until those three earn their keep.
90 to 120 minutes is two to three sessions
This is the study I keep thinking about. Harvard T.H. Chan followed about 147,000 adults for around 30 years across three cohorts, Health Professionals Follow-up Study plus Nurses Health Study and Nurses Health Study II. At 90 to 119 minutes per week of strength work they saw 13 percent lower all-cause mortality, 19 percent lower cardiovascular death, and 27 percent lower neurological death. Past about 120 minutes the benefit flattened.

Ninety to 120 minutes is two to three sessions if you train like most people. I train four to five strength sessions per week. That works well for me.
Shorter and more often keeps me consistent. Forty minutes is easy to start. I lift, I leave, I run the next day without wrecked legs. When I tried two long sessions I skipped more. Life got in the way and one miss meant half my volume was gone.
I read the plateau as good news, not as a limit. It means two sessions already get most of the longevity benefit. Anything past that is for other reasons. For me that reason is habit and keeping my back and knees happy for running. My total is over 120 most weeks. I feel better that way, so I keep it.
If you run and lift, frequency beats hero days. Four short sessions you actually do beat two perfect ones you skip.
Creatine for fatigue, not for size
The Texas A and M trial got the headlines. Twelve weeks, adults 45 to 65, creatine monohydrate versus control. The no-training creatine group still gained about 2.4 pounds of lean muscle. With training plus a calorie cut, strength went up more. Summaries here: ScienceDaily and Medical News Today.
I do not believe creatine does much for muscle size on its own. Two pounds of lean mass on a scan does not change how I look or how I run. I have never seen anyone get big from a powder.
What I do believe is the fatigue part. Creatine helps recycle ATP. That matters late in intervals, late in threshold, late in a 5k when the legs go acidic. I care about holding pace in the last two kilometers, not about the tape measure.
I take it for that reason, for output under fatigue and for cardio repeatability. Protein and training still do the heavy work. Creatine sits behind them. If my stomach or sleep complained, I would drop it first.
If you run, read the study that way. Not as a shortcut to muscle. As a small edge for repeated hard efforts.
What I am actually doing next week
Four to five short lifts, 30 to 40 minutes each. Easy runs judged by heart rate at the start, then by feel after 10 minutes. If Garmin watch or Cirqa flags fatigue, I still start. I only stop if easy pace costs too much heart rate.
Protein stays high. Creatine stays in for the cardio benefit. Wearables stay as advisors, not coaches.
