Use body-weight exercises: The plank workout will improve your core strength.
Squat and deadlift: Guys who are strong in these specific lifts find planks are no problem.

HOLD IT
If you don't have the core strength yet to do a regular plank, you can build up to it by doing a bent-knee plank. If you can hold a plank for more than two minutes with ease, you can move on to these tougher variations.

Ways to improve your plank time
The longer you can hold the plank, the more resilient your lower back will be to injury, and the better your abs will look once you burn the fat off them. Follow these tips for longer plank times.
