There are a lot of widely accepted rules and methods when it comes to weight training, most of us go along with them without giving it a second thought, eg. 3 sets of 10-12 reps is the best way to build muscle and don’t forget to tighten your abdominals when you’re lifting too.
Here are just a few of the most common weight training myths.
Workout Myths – The Most Common Weight Training Lies
1. The 12 Rep Rule
Most weight-training programs include this many repetitions for gaining muscle. The truth is that this approach doesn’t give enough tension for effective muscle gain. High-tension e.g. heavy weights provide muscle growth in which the muscle grows much larger, leading to the maximum gains in strength.
Having longer tension time boosts the muscle size by generating the structures around the muscle fibres, improving endurance.
The standard prescription of eight to 12 repetitions provides a balance, but by just using that program all of the time, you do not generate the greater tension levels that is provided by using heavier weights and less reps, or the longer tension achieved with lighter weights and more repetitions.
Change up the number of reps and adjust the weights to stimulate all types of muscle growth.
2. The ‘3 Set’ rule
The truth is there’s nothing wrong with three sets but then again there is nothing amazing about it either. The number of sets you perform should be based on your goals and not on a half-century old rule. The more repetitions you do on an exercise, the fewer sets you should do, and vice versa. This keeps the total number of repetitions done of an exercise equal.
3. Three to four exercises per group
The truth is this is a waste of time. Combined with twelve reps of three sets, the total number of reps amount to 144. If you’re doing this much reps for a muscle group you’re not doing enough.
Instead of doing too many varieties of exercises, try doing 30 to 50 reps., that can be anywhere from 2 sets of 15 reps or 5 sets of 10 reps.
4. My knees, my toes
It is a gym folklore that you should not let your knees go past your toes. Truth is that leaning forward a little too much is more likely a cause of injury. In 2003, Memphis University researchers confirmed that knee stress was almost thirty percent higher when the knees are allowed to move beyond the toes during a squat.
But hip stress increased nearly 10 times or (1000 percent) when the forward movement of the knee was restricted. Because the squatters needed to lean their body forward and that forces the strain to transfer to the lower back.
Focus on your upper body position and less on the knee. Keep the torso in an upright position as much as possible when doing squats and lunges. This reduces the stress generated on the hips and back.
To stay upright, before squatting, squeeze the shoulder blades together and hold them in that position; and then as you squat, keep the forearms 90 degree to the floor.
5. Lift Weights, draw abs
The truth is the muscles work in groups to stabilise the spine, and the most important muscle groups change depending on the type of exercise. The transversus abdominis is not always the most important muscle group. Actually, for most exercise, the body automatically activates the muscle groups needed most for support of the spine.
So, if you focus only on the transversus abdominis, it can recruit wrong muscles and limit the right muscles. This increases the chance of injury, and reduces the weight that can be lifted.
