I keep a similar mindset to all other core exercises in that I FORCE myself into keeping my back in flexation. This helps. If you're doing it right for other core lifts, I'm surprised rows cause problems.Lowe wrote: Jesus, rowing kills my lower back. After like 2 or 3 km, I can hardly stand it. Probably do it wrong.
Are there any smartphone apps that measure VO2max?
There is no set ratio.MachineGhost wrote: Looks like I had the rest:effort time reversed! Crikey, I must be in worse shape than I thought.
Resting heart rate is a semi-reasonable poor man's proxy for VO2max. (Can I add any more qualifiers?)MachineGhost wrote: Are there any smartphone apps that measure VO2max?

Some pretty good iPhone heart rate monitors can be combined with basic formulas.
Lay on the couch for awhile, measure your heart-rate with your phone. If it is below 60 bpm, then you are doing well. More or less.

"In this issue of the Journal, Schnohr et al. 1 report 3 major findings on jogging and all-cause mortality in 1,098 joggers and 3,950 nonjoggers from the Copenhagen City Heart Study. First, jogging even <1 h per week or 1 time per week is associated with significant mortality risk reduction compared with sedentary nonjoggers. Second, 1 to 2.4 h of jogging per week, with a frequency of 2 to 3 times per week, at a slow or average pace is most favorable as an optimal jogging time, frequency, and speed for reducing mortality. Third, higher jogging times (?2.5 h per week), higher frequencies (>3 times per week), and faster paces are not associated with better survival compared with sedentary nonjoggers, suggesting a U-shaped association between jogging and mortality as well as loss of benefits with higher doses of jogging. Considering the current consensus of a linear dose-response relationship between total PA and health, indicating “the more the PA, the better for health and longevity,”? these findings are intriguing. The good news is that the mortality benefits of light jogging will encourage more people to jog for health benefits as a “practical, achievable, and sustainable”? goal, as the authors have stated."

Below is the typical weekly training schedule for Mo Farah. This involves running up to a maximum of 135 miles per week with no rest days and two sessions every day but Sunday, when he just does an all out 22-27 miles at 5:40 min/mile. This is the life of an elite runner!
