@stevemagness And if you consider fat loss (not simply weight loss), exercise - aerobic and resistance - becomes even more important. You don't want to sacrifice lean mass. That's why waist-height ratio is a much better metric than weight or BMI.

@inside_exercise @TLexercise Sadly not. Sprint cycling research seems to be very thin on the ground, and pro training seems to be largely secret. The best I've found is a 2015 PhD thesis by Wiseman (

@stevemagness And also if you care about performance; all the elite cyclists I know do their intervals about half way to exhaustion (e.g. 2 minutes at 4-minute power). They save the failure stuff for racing.

@nick_krontiris Other than being a bit more complicated to measure, how is this any different than just using waist to height ratio?

@knowledgeiswatt You might want to take a look at a more recent meta-analysis -- see Table 4 in particular. The median TID was much more pyramidal than the one shown here.

@andrew_flatt What's going on with fasting glucose and resistance training? Is this an established phenomenon?

@Alan_Couzens This chart appears to be claiming that a 50 year old of average fitness cannot slowly climb stairs!

@lowcarbGP @DrScottMurray @DrDuaneRD @TheBDA @rcgp @realDaveFeldman @DoctorTro @lowcarb_aus @PHCukorg You don't necessarily have to reduce carbohydrate intake to improve your Trig/HDL ratio. My latest was 1.23 (down from 3.2 last year). Over that year I've continued to eat 60/20/20 carb/fat/protein, but got my body fat under 15% (losing 25 lb). I also minimize *refined* carbs.

@Alan_Couzens @HCHolmberg1 Notably for cycling low intensity was only 60-65%, with around 30-35% medium and 5% high. I find a three-zone system overly broad, but presumably most of the medium intensity work would be at the lower end of that zone, around aerobic threshold.

@scottcarlinpt For cycling it's aerobic threshold work (around 75% max HR). In the gym: sandbag loading, upright rows, Hatfield squats and Hatfield-style split squats (the ones where both feet are on the ground), press behind the neck, pull-aparts, inverse leg curl, ab wheel.

@fmfclips @BradSchoenfeld And don't forget fibre!

@TrainingPeaks Pyramidal for the bulk of annual training, switching to a more polarized approach during tapers leading to target events. But one thing's for sure: dismissing medium-intensity training as 'junk miles' is ludicrous.

@MedBonnevie Notice how his definition of low-intensity training goes all the way up to 85% max heart rate? In fact, I'd say his zone 2 (75%-85% max HR) is actually Tempo training (medium-intensity, i.e. above VT1). So I found it a bit confusing really.

@Alan_Couzens From this, does it not follow that athletes with a high proportion of fast-twitch fibres have relatively more to gain from >VT1 work (to develop their larger mass of fast-twitch fibres), and less to gain from <VT1 training (targeting their smaller mass of slow-twitch fibres)?

@DrMarkBurnley That image implies that commentators used to talk about inorganic phosphate, whereas I'll bet that it's never been mentioned even once in the history of televised sports.

@JSportsSci @GeirJordet @lemmink Sorry, I normally wouldn't do that, but this is for science!

@stevemagness It's like fitting a turbocharger to a tiny engine versus building a much bigger engine with no turbo. Go for the bigger engine, even if it takes a lot longer.

@pbasilstrength And if you don't have access to a Smith machine, try using a Safety Squat Bar holding onto band pegs in the rack uprights for balance (like a Hatfield Squat).
