Circuit, circuit, circuit.
I like to pair with sand bells, ViPR, bodyweight training, HIIT intervals, etc.
Partner 1 = TRX exercise 30-45 seconds while partner is doing an opposing muscle group on the floor or with alternate equipment. Then switch. When I have a big class (big = 8+ for me because I sell this as small group training so I prefer 6), I keep the exercises very simple and only two stations – a TRX station and a non-TRX station (but actually I use CrossCore not TRX because I prefer that product). When I have a normal to small class, I will sometimes do a 3-station circuit – TRX, sand-bell, HIIT drill.
I have tons of examples of this. I’ll dig some up from my youtube channel.
