A 2019 study found that between two groups of 40-50 year old men, muscle mass, strength and power gains were indistinguishable between suspension training and traditional resistance training. The key factor appears to be that providing you trained to concentric failure, it didn’t matter in any significant way, which method of training or rep range was performed. In simple terms, repeat the move until you can’t. Do that enough, eat well and you’re golden. To prove this point, try my TRX leg workout and let me know how those DOMS are the day after.  While there are some limitations to the level of muscular activation in edge cases, for most gym users, a suspension training system will it seems be perfectly adequate to experience hypertrophy.
