There are few tools that work your arms like suspension straps or a TRX. For my money, no other tools can target and work the arms like straps, especialy with all of the different attachments I’ve built 😉
But the tools are only a small part of the effect. The technique you use will always determine the extent of your success.
In this short video I show you why your back and even hamstrings play a key role in a much more effective biceps curl on the suspension straps.
