Just did some Kettlebell swings and kettlebell juggling in during my Kettlebell Conditioning classes rest periods. No set amount or reps or sets during this time. I just wanted to use the swing to demonstrate proper form for the class, while working out some soreness from Tuesday’s “Cindy” workout, for myself.
You will find that “greasing the groove” actually accentuates your training program and strength. Take a break sometimes, without actually “taking” a break.
