I love suspension trainers. I typically implement suspension exercises into my routine, but it's nice to have a full TRX (Jungle Gym) workout when you're in a time crunch.
This one I like to call Glute/Core 180, because you perform 180 reps. Perform each exercise and it's given reps consecutively without rest. Once you finish that last rep, rest 1-2 minute and repeat for 3 total rounds.
10 prone leg curl
10 hip bridge
20 mountain climber
05 jack knife
10 plank double hip abduction
Burn baby burn! Have fun with this!
