Speed ladder variations 1 leg jumps

Purpose of the exercise

Plyometric exercise to improve single-leg explosive power, dynamic balance, ankle stability and neuromuscular control. Trains the thighs (quadriceps, hamstrings), glutes (especially gluteus medius and maximus), calves and hip stabilisers. Develops proprioception, responsiveness and functional strength for sports performance. Also effective for identifying and correcting strength differences between left and right.

Supplies

• Speed ladder (agility ladder) - flat ladder with 8-12 sections
• Flat, stable surface with good grip
• Sports shoes with good ankle support and cushioning
• Sufficient space (minimum 5-6 metres length, 2 metres width)

Starting position

1. Place the speed ladder flat on the ground
2. Stand at the beginning of the ladder
3. Stand on one leg with slight knee bend
4. Lift your free leg slightly off the ground (knee bent at 90 degrees)
5. Weight on your front foot of the stand leg
6. Arms bent at 90 degrees, ready to move along
7. Core tense, gaze forward

Implementation

Basic variation - Forward 1 leg per box:

1. Jump with one leg into the first box
2. Land on the same foot with gentle knee bend
3. Jump explosively through to the next box
4. Keep up the pace with minimal ground contact time
5. Actively use your arms for balance and momentum
6. Jump through all boxes until the end
7. Switch legs and repeat
8. Rest 30-45 seconds between sets
9. Repeat 3-4 times per leg

Other variations:

• Alternating hops: Switch legs at every jump (left-right-left through the boxes)
• In-Out 1 leg: Jump in box, jump wide out, jump in next box (all on 1 leg)
• Zig-zag: Jump diagonally from left to right through the squares on 1 leg
• Backwards: Jump backwards on 1 leg through the boxes
• Double contact: Two jumps in each box before moving to the next one

Points of interest

• ✓ Always land on your front foot with soft, bent knee
• ✓ Keep your hip, knee and ankle in one straight line
• ✓ Make short, explosive ground contacts (jump like a spring)
• ✓ Keep your torso stable and upright
• ✓ Actively use your arms for balance and extra strength
• ✓ Constantly tighten your core and stance-leg buttock
• ✓ Breathe calmly during the exercise
• ✗ Avoid inward-falling knee on landing (valgus)
• ✗ Don't let your hip sag or tilt to the side
• ✗ Don't land hard or flat with knee outstretched
• ✗ Don't jump too high, focus on speed and control
• ✗ Don't touch the ladder with your feet (precision)
• ✗ Don't let your free leg swing uncontrollably
• ✗ Don't look at your feet, keep looking ahead

Progression

• Start: Forward 1 leg, slow pace, 2-3 repetitions per leg
• Advanced: Increase speed, 4-5 reps per leg
• Heavier: add different variations (alternating, in-out)
• Additional challenge: Complex patterns (zig-zag, backwards)
• Tempo variation: Maximum speed with perfect technique
• More complex: Combine multiple variations in one set
• Advanced: Add rotations or 180-degree turns between boxes
• Expert: Reactive drills (jump on auditory or visual signal)
• Heaviest variant: use weight vest (only for very experienced athletes)

When this exercise

This exercise is suitable for advanced to elite athletes who want to develop single-leg explosive strength, balance and sport-specific agility. Ideal for footballers, basketball players, volleyball players, tennis players and runners who want to work on explosive strength and ankle stability. Very effective in the final rehabilitation phase (return to sport) after ankle injuries, knee injuries, cruciate ligament reconstruction or hamstring injuries to restore functional strength and build confidence (only after physiotherapist or sports doctor approval). Also valuable for injury prevention programmes and identifying weak points between left and right. Not suitable for acute injuries, chronic ankle instability or insufficient base strength. Build up first with two-leg ladder exercises, static single-leg exercises and simple single-leg hops before performing these advanced variations. Always start after thorough warm-up with dynamic stretches and build-up jumps.
