When completing the circuit at the end, I would like you to set a timer for 12 minutes and work as many times through it as you can in the 12 minutes. There is no function on Skimble for me to write it like that so i've used 7 rounds as a guide.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
