You can do a lot of hybrid training at home. You do not need a full gym — a few well-chosen pieces of equipment and space to run cover most of it.
Priorities
1. Running
The most important training for most hybrid races needs only shoes and a road, path or park.
2. Kettlebells or dumbbells
Swings, carries, lunges, squats and presses. A couple of weights covers a lot.
3. A sandbag
Lunges, carries and other functional work. Many can be filled to different weights.
4. A wall ball
Wall balls need a ball and a safe wall or target. Check you have the space and height.
5. A pull-up bar
Pull-ups, hangs and core work.
6. Resistance bands
SkiErg-style pull-downs and other accessory work. See no SkiErg at your gym.
Nice to have
- A rower: race-specific and good for fitness.
- A barbell and plates: for heavy lifts.
Hard to do at home
- Sleds: see training the sled without a sled.
- SkiErg: expensive and needs height.
Try to use a gym for these now and then.
A home session
- 5 rounds: 800 m run, 15 kettlebell swings, 20 m sandbag lunges, 15 wall balls.
