"Hybrid training" refers to a training method that simultaneously develops two opposing elements: "strength" and "endurance." It was once believed that aerobic exercise would cause muscle loss, but today, this style, which combines powerful power and high stamina through a scientific approach, is attracting attention. His performance can be...

A person asks Sadhguru, “How much weight training exercise do you recommend?” And Sadhguru answers, “Weight training is not useful, but do 25-50 Surya-Namaskars, it is complete exercise.” First of all, I am not sure why anyone would ask someone like Sadhguru, who is most of the time, in another dimension, a question on exercise and weight training. And secondly, Sadhguru is just plain wrong. Weight (or strength) training is one of the most important aspects of exercise regimen you can include in your daily or 3-4 times a week physical activity because there is great science behind its benefits. I advise my obese or sarcopenic (very poor muscle mass in advanced liver disease) patients to include weight training to improve clinical outcomes. The highest level of scientific evidence showed that standard muscle-strengthening activities were associated with lower risk of death in patients with non-communicable diseases – including cardiovascular disease, diabetes and lung cancer. Another metanalysis showed strong evidence for a considerable risk reduction of strength training for 60 minutes a week, on all-cause death (−15%), cardiovascular disease death (−19%), and cancer death (−14%). See here: here Sadhguru says the older we get, the better we do not weight train. He is again absolutely wrong. The findings of another systematic review/metanalysis support power (strength) training as an effective therapeutic intervention for improving physical function in adults diagnosed with frailty (poor physical function in old age) and patients with chronic medical conditions. See here: In fact, another study on strength training, this one again a metanalysis, concluded that strength training interventions can be used as a non-drug treatment for hypertension (!), as they promote significant decreases in blood pressure. See here: Strength training also reduces significantly, chronic inflammation as shown in another high quality systematic review and meta-analysis. See here: Resistance/Strength training improved muscle mass and muscle strength, thereby improving performance status. Improved performance status is a wonderful benchmark for an active and healthy life. See here: Even in fatty liver disease, independent of weight loss, exercise training was associated with 3 and a half times more meaningful treatment response towards lowering liver fat. Strength training is a powerful tool to maintain liver health. See here: and here Now Surya Namaskar. Surya Namaskar or Sun Salutation is a sequence of around twelve yoga poses connected by jumping or stretching movements, varying somewhat between various Yoga schools – which means, it has no regulation or standardization unlike weight training. In Iyengar Yoga there is a way, in Ashtanga Vinayasa Yoga there is Type A and B and there are other types followed by other schools or Yoga teachers. Along with the stretching and jumping, which is done is a slow and steady manner, the practice includes chanting a “mantra” calling out twelve names of the Sun God. In its classical form, Surya Namaskar is not an exercise, and is not aerobic. The energy cost of exercise is measured in units of metabolic equivalent of task (MET). Less than 3 METs counts as light exercise; 3 to 6 METs is moderate; 6 or over is vigorous. American College of Sports Medicine and American Heart Association guidelines count periods of at least 10 minutes of moderate MET level activity towards their recommended daily amounts of exercise. For healthy adults aged 18 to 65, the guidelines recommend moderate exercise for 30 minutes five days a week, or vigorous aerobic exercise for 20 minutes three days a week. Surya Namaskar in its classical form has a measly 2.9 METs and in its rigorous form (some people perform mutated highly active forms of Surya Namaskar to make it feel like an exercise) can go up to 7.4 METs – which requires a lot of jumping and little stretching and no time to chant the Sun God names - does not even come close to strength training by any margin. Those who are part of the Surya Namaskar and Yoga cult would provide anecdotal experiences on its benefits (please see comment section) through non-classical forms and would call it an “exhilarating experience.” Experiences are not scientific, evidence are. Many Yoga journals and some dubious and third rate Ayurveda journals have also have published on such experiences in small group of patients, which are not validated or published in better journals [like this junk here: There are no metanalysis level data to prove effectiveness of Surya Namaskar as beneficial as aerobic exercise or better than strength training as Sadhguru claims. Do Surya namaskar if you are doing nothing. But upgrade to strength training if you want something. And stop listening to pseudoscience peddlers who speak religion and culture for your healthcare needs. Sadhguru suffers seriously from Dunning Kruger fallacy: a type of cognitive bias, where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs because of the fact that they don’t have enough knowledge to know they don’t have enough knowledge.

Do you need to train heavy to build muscle? 💪 For years the mantra was you need to go heavy to build muscle. Or you needed to go heavy to stimulate large type II fast twitch fibers but go light for more reps to stimulate smaller type I fibers. But new research has challenged that dogma. Several meta-analysis have shown similar muscle growth with low loads vs high loads when set number is matched & proximity to failure is similar (PMIDs: 28834797, 35015560, 33312275, & 33433148). While muscle hypertrophy was not different between high and low load training, strength increased significantly more with high load training in all these meta-analysis As far as targeting fiber types, it becomes kind of irrelevant when you take an exercise close to failure because fiber types tend to be recruited in order from smallest to largest. So with high load training, small & large fibers get recruited quickly but you don’t do many reps. With low load training, you initially recruit smaller fibers but as the muscle fatigues it is forced to recruit the larger fibers as the exercise is taken close to failure. The net effect is that taking sets close to failure with high or low loads produces a lot of muscle activation and similar hypetrophy The take home is, do what you enjoy if muscle growth is the goal. Just make sure you train HARD & go close to failure (within a few reps) & do enough total sets. But if strength is a priority you’ll need to train heavy & be careful going to failure as it can impair strength gains From my first conversation with Andrew D. Huberman, Ph.D.
