As soon as a student gets serious about competing at Carlson's i try to give them advice about strength training,nutrition,flexibility and cardio.
Many of the students at the gym don't need the advice,they are already well versed in how to be in their best shape.
Others however take the advice and work on it.
There are some though that say "I don't want to lift weights,it'll slow me down", or, "Weight training stunts your growth",or "I will only do bodyweight excersises,i won't lift weights".
Sometimes they are under the impression that the lighter more technical BJJ Champion's just do Jiu Jitsu and a bit of running.
They have been filled with 1970's 'old wives tales' about using resistance training."The muscle turns to fat when you stop training", "I don't want to get big" LOL.
Well here's a few thoughts-
1. Your body doesn't know what creates resisitance-it doesn't know whether its lifting flesh or iron. A kilo of bodyweight is the same as a kilo of steel.
2. Every professional athlete uses resistance training (weights) and it doesn't matter whether they are lifting iron or flesh.They are creating resistance and lifting it.It is the 'manner' in which the resistance is lifted that is the key to how beneficial the training will be to the athlete.
3. Even sports that eschewed 'weight training' because of archaic beliefs and demented old fashioned coaches without any idea of strength training (i.e. Football and boxing) have come of age and now every pro footballer and boxer will use resistance training to build strength.
4. The stronger a muscle,the more explosively it will be able to contract,the secret is training the muscles in multi compound movements to contract together,rather than in isolation like a bodybuilder.
5 Finally, It is of huge benefit to any athlete to be as strong as he/she can be in their given weight class.
For the smaller,technical guys who don't really believe in resistance training,here is Cobrinha showing his workout.
