ok, i looked
. Do you feel you're getting a better workout then going to the gym?
Difficult to say. The TRX workout is strictly strength, so it's really demanding. There is no such thing as pump or whatever. The workouts with the TRX are very intense, so in this way, it is "better", as there is no way to 'cheat' around the intensity, like in the gym.
On the other hand, even though i will do the 12 weeks program only with the TRX, i will not cancel my gym membership. One legged squats are demanding, but barbell squats are better for mass. Also deadlifts.
But, i will never train my abs without the TRX anymore, i have had the best ab training in my life with that. There are certain other exercises i will incorporate into my usual gym workout after the 12 weeks. For strength, you could go only TRX i think, but for mass some weightlifting will be necessary too.
But i really don't want to miss the TRX, it's a great workout for building functional, overall body strength. Better than weights in this part. No imbalances as well.
