Looking to become “springier” in your tumbling?
Try pairing a heavy lift with a similar jump. Ex: heavy goblet squat / front squat / back squat paired with a box jump.
If you are new to lifting, focus on higher rep ranges before adding weight. This will help you build more muscle and endurance. Ex: 3 sets of 8-12 hard squats rather than 3 sets of 3 hard squats.
If you are an experienced lifter (more than 1-2 years of consistency) then you may benefit from adding more weight and keeping the reps lower.
