    Cycling and weight loss

    This is directed towards the goal of 'weight loss', not athletic improvement or long term endurance. As you said earlier, an exercise session of about 30 minutes would typically burn about 200-400 calories - depending on intensity, and that amount is usually 'stored' (unless significant work...

    Cycling and weight loss

    The idea is that for weight loss, you can exercise for a while (say about 30 minutes) without the need to consume more calories (and without the need to consume beforehand) - just use the glycogen that is already stored in your muscles / liver / blood to fuel the energy (calories) burned doing...

    Aero bike - new road cyclist?

    For use by a beginner recreational road cyclist, I recommend a regular 'road bike' that has comfort and reliability. That type of bike would likely be useful for most riding situation, be enjoyable, and be good for exercise. A true aero bike could be tricky to handle on windy days (due to wide...

    Question Optimizing Cyclists' Nutrition: Strategies for Performance

    A major consideration is the person's 'physical starting point' - nutrition considerations depend on items such as: Is the person trying to lose fat and generally become more fit. Is the person already fit and does not have excess fat. Is the person using cycling as a recreational activity. or...

    Cycling with anxiety

    The elevated heart rate is needed to cope with (tolerate) the increased activity level - no adapting or getting stronger occurs during the session of exercise. For people who are healthy and have the necessary hormone levels, the physical stress from exercise can (with rest and recovery) induce...

    Low Carbs Intermittent Fasting Diet

    Carbs are said to provide about 4 calories per gram. At hard-racing exertion level, burning 600+ calories per hour is likely. So in long duration events it would be necessary to 'fuel early' and 'fuel often' to keep up with the burn rate. In race conditions it would be unlikely to be able to...

    Cycling and weight loss

    This article provides a lot of related info - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3577439/ An important consideration are the goals of doing the exercise - weight loss, performance increase, general conditioning, etc. Also, how soon after an exercise session do you need to perform other...

    Cycling and weight loss

    Every day would be best, but done at a moderate intensity and duration that allows you to be fully recovered by the next day. Most important is to not increase your daily calorie intake - DO NOT treat yourself to a high calorie snack as a 'reward' for doing the exercise, and you probably do not...

    Spinning instructor

    First, as the class leader you need to know and understand the goals and abilities of the participants. Some people do spin-class just as exercise, without any actual outdoor cycling. It can also be a social activity with lots of talking during the easy portions of the session. It's...

    Does anyone ride 42 teeth inner chainring on a regular basis any more?

    Probably it's used on 'old school' setups. If there's a large enough gear on the rear, then 42 is fine for a fairly strong rider on steep hills. I stopped riding several years ago, but 42X28 was my low gear.

    Diagnostic Advice

    If you have the tools and time, the best would be to remove, clean, and lube all those parts. Pedals, crank arm attachment to BB spindle, BB bearings. Simple first check would be to verify tightness of the BB retainers, and crank arm retainers.

    Time Trial Bikes Safety

    Is the safety concern about the individual rider of the TT bike, or about safety of other nearby riders and spectators, etc. ?

    Commuter tyres for gravel bike (speed + grip)

    Can you get 'road tires' with the appropriate width for the rims? Probably similar width to gravel tires. The contact patch is dependent on the pressure, so even a fairly wide road tire will be fine when properly inflated for road use. I've done commuting (including snow) and 100 mile rides on...

    Are tall riders at a disadvantage for GC wins?

    Maybe there is an aero advantage for shorter riders due to less leg frontal area exposed to air resistance. That might also apply to upper body area.

    Why are climbing cadences often lower?

    'back in the day' bikes had 10 speeds with 5 cogs in the rear. Having a large rear cog would then only allow 4 other choices for the rear. They would rather 'tough it out' on climbs rather than not have the best ratio for the longer flat / rolling sections.
