Y'all might have seen that I started IKU Kettlebell Routine Program #1 8 weeks ago. The booklet as 4 12 week training programs - all good stuff!. Also have been increasing ZONE 2 aerobic capability. Taco has a ZONE calculator in Monster also. But the universe seems to reinforce topics to me at times. This time is about better aging. ( I'm 70, so this is a hot topic for me). I recently bought Taco's FAST IRON. In there has writes" For: general trainees who want to be muscular, strong, and able to move fast, especially anyone from their thirties on who wants to defend their fast-twitch capacity rather than watch it drain away." "It builds muscle and strength while training your ability to produce force quickly. In ordinary hypertrophy training the lifting phase is slow or merely controlled. Here the lift is explosive, which trains rapid force production that conventional work neglects, and the tempo research supports a fast lift paired with a controlled lowering as a sound general setup.[11][13][14]" FAST IRON has a list of studies (Taco always has the research), but I didn't see this study that reinforces Taco. Today, from Geoff Neupert's newsletter "Recent research out of the CLINIMEX cohort – published in Mayo clinic Proceedings in 2025, nearly 4,000 people aged 46 to 75, tracked for a median of almost eleven years – found that muscle power was a far stronger predictor of dying than muscle strength was. The men with the least power for their bodyweight were 5.88 times more likely to die than the men with the most. Then the researchers ran the identical analysis on strength. Grip strength. The number everybody quotes. It didn't reach statistical significance. Same people. Same eleven years. Power predicted who died. Strength didn't. I'll be finishing IKU Routine # 1 and switch to FAST IRON in a week or so.
