In this video we see a great circuit-based training presented by @curtis_demont as a selection of lower body exercises augmented by Fit Cuffs.

Exercises in display:

0:16 Walking Lunge
0:20 Squats Jump
0:27 Push-up
0:42 Inch Worm
0:39 Horizontal Jump Squat
0:49 Lateral shuffle

So, as long as the gym is closed, we advise you to utilize your favored BFR tool and move your exercise routine to urban areas, nature or for some higher restricted regions as home training.

But if you do not supplement your BFR training by any kind of external resistance tool, like elastic bands etc., most people need to consider how to fatigue of both type 1 and type 2 muscle fibers.

As a rule of thumb, to target type 1 muscle fibers, you need to train at lower intensities, but perform higher reps and probably also more sets.

Subsequently, you can also consider the force-velocity relationship like doing force-full movements like sub-maximal Squat Jumps to achieve the fatigue of type 2 fibers at a rapid rate. This is because, if exercises are conducted at higher velocity this leads to greater exhaustion of fatigue sensitive type 2 fibers.

Any thoughts or precautions on BFR in combination with higher velocity based exercises like Jumping?
