Weight training. What burns more calories? Low rep heavy or

edited October 6 in Fitness and Exercise
I just switched over from a low rep heavy(4-5 rep) to a high rep (10-12) light lifting routine. My workout times are roughly the same time and my cardio hasn't changed. My diet has in general, been the same.

But I've noticed my weight has been creeping down slighly faster. (I"m not complaining! :drinker: )

Just wondering if the swtich to a high rep count is the factor here? Should be dong more "work" as you are doing more reps. VS a low rep at heavier weight. More calories burnt?

I ask because this site's determination for calories burnt while lifting is pretty vague to begin with. It's certainly not going to make the distinction inbetween high / low rep. Especially when the time spent doing it is roughly the same.

    It's pretty high on the list of importance to me.

    There are better ways to create a calorie deficit. This is analogous to doing distance running for leg strength.

    But whatever floats your boat.

    Correct. If that was my only goal. But it's not.

    what are your goals?

    Operate at a lighter weight, be stronger, be faster, be leaner, retain as much muscle mass as possible.

    So far, from my observations, I've on track to accomplishing this. The faster aspect is subjective but I seem to be faster

    The muscle mass retention will be roughly determined at my next BF measurement (soon I hope)


    Is there any rough calculation of how much more calories are burnt via high rep vs lower rep? I also triple set my lifts. 2 lifts and one plyometric per triple set.

    The more reps you do, the more you raise your hear rate and the more calories you burn. Higher reps are better for hypertrophy (~8-12 reps). Lower reps are better for strength.

    So, best overall range is 8-12.

    However, if you go too much more than 15 reps then you are really cutting into growth potential.

    Timing of reps matters too, take about 3 seconds down, a 1 second pause, then 2 seconds up. Each rep should be around 4-5 seconds.

    Muscle mass is best retained at the lower rep ranges.

    I honestly have no idea how to calculate calories burned, it's not something I've ever done. Assuming you are on a routine that isn't highly variable, I don't think it matters much. Just keep calories consistent, and lower them a bit if progress stalls.

    4-5 seconds per rep? I'd be in the gym forever.

    Upon this rock.

    I just got done doing a heavy/low rep routine. I just happen to start a high rep/lower weight cycle.

    you should not be allowing gravity to take the weight down for you. do what he said, and you'll notice the work out being more effective.

    Better results this way for sure.

    You may end up using lighter weight than you did before to get into your rep range. The way I see a lot of guys doing reps in the gym (far too fast) they're basically only getting 1/2 reps worth of work in each of their reps. When you don't take enough time on bringing the bar down (on bench and curls for example) you are not putting the muscle under tension for half the lift.

    Slower reps (if you are currently going too fast) will increase gains and strength.
  • i find intensity to be the determining factor of how hard I worked out. Usually lower weight at higher reps is higher intensity work because I take shorter breaks between sets, thus keeping the heart rate up for longer durations. I make my higher weight lower rep workouts more intense by taking only 60 sec breaks between sets. If you took 3-5 min rest between sets I would think you are burning fewer calories. Not sure of any specific studies on this so difference in calories burned may not be significant enough to matter.

    Intensity is determined by the number of sets, weight,reps, rest between sets, reste between exercises, and pace of the reps.

    If you increase weight, sets or reps, or decrease rest times and slow the pace, you are increasing intensity.


    Generally speaking it's easier to increase intensity by slowing the pace of reps, increasing reps or decreasing rest than it is to increase weight, just because eventually form will suffer with increased weight.

    Do both.
    You should do heavy weight lifting so you build more muscle (6-8 reps) and then when
    you do light weight (12-15 reps), you will burn more weight.

    P90X and Chalean Xtreme was created base on this concept. Most of the fat loss are on phrase 3 of the program.

    Fast reps will increase strength as well. Explosive-strength..With explosive-strength you want an optimal bar speed in the yeilding portion of the lift and you want to switch quickly from stretching to active contraction, utilizing the elastic potential of the stretch for raising the power of the subsequent contraction. If you lower the bar to slowly you limit the amount of energy that can be stored..And if you pause between the yielding and overcoming phases you lose energy gained as heat..This will not result in a more powerful contraction and you will not be taking advantage of the stored energy from the pre-stretch.

    Well if you're doing more reps and it's roughly the same time, then you rep speed has to be faster than when you were doing 4-5 reps. Since lifting higher reps is more for muscle endurance, you are burning a few more calories lifting more reps. Also your recovery time is probably faster too since the intensity isn't as high. So your heart rate probably stays up higher too.
    And you won't retain as much water either.

    To the OP,

    I just started working out again after a long (3-4 year) hiatus. I am doing mostly weight training and planning on adding in a couple of hiit sessions as soon as I acclimate myself back in to the weight program. I try to thoroughly research any big life change I plan on making and getting fit again is no different. I would highly recommend the book by Lou Schuler and Alwyn Cosgrove called the New rules for lifting. Without trying to make it seem like I work for the authors, let me tell you what I got out of it. The new rules are actually the old rules revisited, they stress big compound movements and constantly changing your routine. They also have a program that can take you through a whole year of workouts but it is also easy to make your own routine out of the sections. I have only just started this program but I have read the whole book and it was entertaining and seemed technically sound. Good luck with your workouts!

    Cheers,
    Collin

    Actually I've been more sore. I can't say to the water retention though. But the HR has definately been higher. I'm more gassed at the end of my triple set

    I wonder. What would actually burn more calories. 10-15 reps at a lower weight or a 2-4 rep at 90% of your max 1 rep maxium?

    Not saying you're wrong, but if you're going to throw a statement like that out there, you could at least also enlighten us with the facts, otherwise it's not really that useful, and is borderline trolling, which I assume (hope) wasn't your intention.
