In this video Albin shows a wrestling based Single Leg Takedown For BJJ. Along with the basic grip fighting to set it up.
A single leg takedown works incredibly well in BJJ as long as you understand how to deal with the grips and have a proper setup.
Also, on a side note. Whether you prefer Judo style or Wrestling style takedowns. Learn takedowns! Even if you’re not the best guy with takedowns, learn how to pull someone down to the ground and be offensive from your back. Either way, learning how to start from your feet is really important.
